Buckys C++ Programming Tutorials - 36 - Multidimensional Arrays

[@benjamintan90s]

Thank You ! you explain something in 6 mins that my lecturers cannot explain for weeks

[@asmaabdulmajeed5689]

+Tan Ben  i agree

[@rahulv4943]

Maybe, because you don't pay attention there?

[@imabrony.cryaboutit.2274]

Albert Einstein said "If you can't explain it simply, you don't understand it well enough." Maybe you should point your teacher to Bucky's tutorials... :P

[@giovannicorraliza4393]

@@rahulv4943 nah brah my professor seem like they barely understand it them self

[@davidcastle8476]

I have been following your tutorials for some time to supplement my class questions that my teacher has trouble explaining in a coherent way. I 100% love what you are doing. You teach in a concise to the point manner with common sense and good analogies. I wish school professors being paid big bucks could do the job of you providing these free tutorials lulz.

[@togmeister8604]

These tutorials get easier the more you do. On first day I got 6 tutorials done and now I've got currently 30 tutorials in one day.

[@aceuayylmao420kappa]

Togmeister I've just been replaying them for about a month, making sure I have everything he is teaching us figured out (for the most part, you learn new things everyday :p) after that I will move on and try making my own projects

[@tehkid93]

Orbit™ a month? wtf? do you like pass 2 tutorials a day or what

[@togmeister8604]

tehkid93 He said he replays them.

[@SetYourHandle3]

Orbit™ Hey, in case u are interested, there is an app on android which uses Bucky's videos to teach people C++ and after a short amount of the video it asks u questions about what Bucky said or asks u to complete a syntax,etc. its very useful................................................................... I hope bucky isnt mad about them using his videos. I mean, its a non-profit app based only on donations and bucky receives his part from youtube views and ads before video starting. www.sololearn.com/Course/CPlusPlus/

[@soufianesalhi8802]

+Togmeister just like me

[@SenzoDlomo]

Man, we miss you Bucky Roberts, helped me learn Java and now C++, your videos are never going out of date, this is over 8 years later and still relevant and helpful

[@heisenberg7945]

10 yrs now

[@fatima-oy7gk]

You teach amazing!!!! I thought I was never gonna understand this concept. You explained in 6 minutes what my teacher couldn't in 2 hours.

[@KaletheQuick]

Bucky, holy crap. I have been watching your tuts for years. You are the best. Thank you for teaching me so much!

[@Limpuls]

You could just write multi array like this ... = {{2, 3, 4}, {8, 9, 10}}; It's easier to visualise it this way, than type it all out in one line.

[@edwarddoofenschmirtz4436]

does this work in DevC++ as well?

[@calvinbeckingham586]

All of your videos are so helpful Bucky, thank you so much for your work! I would be completely lost in my Engineering programming unit if it wasn't for you! I will definitely recommend your tutorials to anyone struggling with C++.

[@carlaludgate6597]

"it's just like inception" - haha! dude you rock

[@donabood4467]

Carla Ludgate and

[@yamuson08]

you have been my C++ professor all semester. I wish I could save the money because I learn more watching these videos.

[@kmwakutuya]

Easily the best explainer of code i've ever seen. I dont understand why everybody else has to be so technical and professional about this stuff because then people get lost. You speak with normal lingo so everybody can follow. Thanks

[@jasonf8129]

you have made my life so much easier. currently taking my first C++ course and these videos are such a big help. Thanks Bucky

[@Frances3654]

Yo dawg, I heard you like arrays, so we put an array in your array, so you can store elements while you store elements!

[@jimw3220]

I'm watching this during a test. Oh shit, a TAs coming!

[@czechchineseamerican]

If you were really all about that programming life, you would have been watching this during your biology test, so your TA wouldn't have cared ;)

[@iVipulSurvase]

Thanks a 1000 times. Even my professor couldn't explain this concept so clearly.

[@danielhaslam5179]

For the first three minutes of the video this was confusing. But when you visually plotted the array it all came together. Thanks Bucky!

[@alihassan2203]

I love you bucky I was confused from weeks and you just give me answer in 6 minutes

[@ytarame]

Saved my life man,I've been trying to do it but it wasn't working. I was forgeting about the "," between the rows.

[@problematicpunk]

This tutorial series has been really helpful while learning Game Maker. Love your tutorials as always Bucky! I actually learned python from you, so this is my 2nd tutorial series ;) I love python. Probably my favorite language.

[@yasenbonev7879]

Watermelon.exe never disappoints

[@Golden2Talon]

lmao didnt even notice that one

[@Trolld]

watermelon.exe has stopped working

[@mirandac8712]

You're the best programming instructor I've ever had -- with one exception, when I got my doctorate at a pretty famous ivy league school :)

[@allastname9143]

So you have a doctorate from a famous ivy league school, with at least some programming instruction at doctorate level, yet you're here getting instruction on the very basics of C++? I call shenanigans on you. Lemme guess - you start high school next year...

[@mirandac8712]

Yeah that must read strangely! My degrees were in music and finance, so we took courses haphazardly. You'd be surprised (or maybe not) how many people who go very far never learn the fundamentals. Anyway my point was these tutorials' easy-going charm doesn't sacrifice precision or accuracy. Academia could do with a lot more of that approach.

[@allastname9143]

Fair enough. I jumped to a conclusion (happens a lot on KZbin comments that people mis-represent themselves). Where I study doctoral students aren't involved in undergrad classes so it seemed even more unusual to me. Kudos for going outside your comfort zone!

[@aestheticamorous]

This is exactly right. If I ever make big video games I'll be giving Bucky a percentage of what I make that's for sure. He deserves it.

[@Lolatyou332]

You can think of a multi-dimensional array as a menu system, where the first row is start/menu/preferences... Then you go into those each separately, start-{quit, play, stop} menu-{stuff}

[@satyamlnu2798]

You are doing a wonderful think Bucky,keep it up

[@iXenoCider]

When I first started learning, boy did I want to do the same thing... Now I just go through them like butter and instead of hoping for something like that, I just hope that i learn something awesome! Which is normally found in Bucky's tutorials lol

[@idonotwanttonamemychannel217]

Random fact: there are NO multidimensional arrays in C++. I read (in the best-seller C++ book of 2013, sorry I forgot the name) that there are no such things in C++. The way that C++ handles these, they are really called "arrays of arrays". But the term "multidimensional arrays" has been used so much that the term is essentially accepted. Don't worry you can say it by that term but I just felt like telling anyone reading this a fun fact :p

[@idonotwanttonamemychannel217]

***** what?

[@idonotwanttonamemychannel217]

Sorry I'm confused as to what you are saying. Are you saying that the C compiler doesn't handle arrays of arrays? Because they do... otherwise it wouldn't work..

[@idonotwanttonamemychannel217]

C handles arrays of arrays. C++ also handles arrays of arrays. There are no such things as multidimensional arrays.

[@Rin-qj7zt]

+MrKillius24 _"C does not handle them the compiler does arrayone[]arraytwo[]"_ this is actually two separate sentences. it's a bit confusing. _"C++ and the compilers do handle 2d-3d arrays as what they are different type of arrays."_ This doesn't look like a valid sentence in english. it looks like you just stuck "different type of arrays." at the end of the sentence "C++ and the compilers do handle 2d-3d arrays as what they are" it was just bugging me. >.> sorry, i have no life.

Hey dude, you rock man! =) Greetings from Bulgaria! I'm a huge fan of yours and thanks for all the tutorials you have posted.

[@talhaahmed3895]

Best Tutorials For Life Watched Each One Of Em!

[@Jack-4242]

this is very helpful this way you can create a map in a game and check the coordinates and so check if the character collides with the wall or with enemies or something like that

[@muhammadwasi5460]

Dude you're the best .... see you in your dream.... You're videos are just mesmerising peace!

[@aurelliaqaleesya7825]

really easy to understand:) Hello from Malaysia

[@jairoacosta8940]

thanks, i came from the GameMaker engine where array[ column ][ row ], all these short videos are nice references.

[@CryosFOXHOUND]

This made things much more clear to me. Although I'm curious as to how we would write the multi dimensional array so that we can take input from a user and put it in the array. And then loop asking for input until terminated.

[@BobFoxhound]

These tutorials are very good - An educator

[@megispahiu2982]

u explained this in such a short video. is really easy like this. thank you

[@freshparker2459]

You literally just saved my life! This guy that I am learning c++ from on Udemy can totally suck ass sometimes and not explain things right. But you, my friend, are the bomb! Do you teach on Udemy?

[@DaanSnqn]

It's a matrix. Take the red pill, Sally!

[@UltraAnalisis]

Thanks, many of your videos are great

[@xaviadenson2097]

Dude thanks so much for making these videos!!

[@grvin19]

That made a surprising amount of sense

[@rabibwolverine]

How to manipulate dynamic multi arrays? I mean with pointers? I would like to load 2 arrays to the multi array in order to fill the 1st column ad the 1st row

[@Stiflex]

How do you make a specific multidimensional array? For example, it must contain from 2 to 8 rows and columns. How do you do that?

[@kaizhang6768]

saw your comment. But dont really understand ur question..

[@Stiflex]

an array that generates from 2 to 8 numbers.

[@muhammadshamyl9182]

Smite Gaming Hey man, you're gonna have to use the srand() function and add your limit. simple.

[@dahen6872]

and include cstdlib

[@Jack-4242]

@Nahiyan12 ah, ok i always wonder you need functions to build functions, so how were the first functions made? only by putting Zeros and Ones together in a special order?

[@Howtodothatshit]

@Herp Derpingson It depends on the compiler. Real compilers have limits, sometimes fixed and sometimes dependent on available storage (RAM or hard disk).

[@nicolasvalverde3270]

Why is it referenced column then row? Wouldn't it be easy to follow the mathematical (x, y) (column, row) pattern?

[@TheGodzilla1955]

@JakobRobert00 the first programming was done with a magnetized needle and a steady hand.

[@toringedotno]

Could you use multiple data types in multidimensional arrays? Like in PHP where you can mix strings and integers?

[@informativecontent4778]

lolx me too great

[@aljodewi]

so we are using 1's and 0's to create a program to use those 1's and 0's Byteception?

[@sajadtorkamani9399]

Very well explained!

[@preciseestimatingltd2579]

Interesting how there's no fail-safe in c++ for accessing elements which are out of range e.g. int main(){ int arrayMultiDim[4][6] = { {23,11,4567,83} , {47,2,99,877,31,88} }; cout

[@ZayMeisters]

This video helped me with a bug in my code. THANK U SO MUCH😭😭😭😭

[@TheKaeru1000]

Can anybody tell me how to declare dynamic double array within a class??

[@heavym3tal]

Does time in the lowest array "move" slower than time in the highest array?

[@zoereed4010]

Why does your 2X3 array hold 3 values for both the row and column values

[@peebleish]

Hey Bucky, can u also tell us how to return a multidimensional array from a function? I just can't make it work.

[@ejudeeus]

does anyone can help me? im dealing with 5 dimension array. but it gives me bad mem alloc. done in c++ totalArr[i][j][k][l][m], each have i j k l m = 60. do i have any other ways to solve this problem?

[@libertynindependence]

So is this how you can put a matrix in C++? That's obviously what it is, but are the properties the same?

[@Qazqi]

Implementations are recommended to accept a maximum of at least 256 dimensions, but that's not a requirement.

[@NorthboundFox]

So, these are basically the C++ equivalent of a matrix grid?

[@NOS187]

Hey bucky, i cant seem to find the video were you told us which new compiler you are using now. Do you mind telling which it is? Im using Dev-C++ currently.

[@LurkrulDoesThings]

He explained that in an earlier tutorial. By default the updated c++ automatically returns 0 in main whether it is there or not.

[@shikhagupta7401]

How to take inputs in an array until enter is pressed and then output them

[@artashes999]

Are three dimensional arrays popular in everyday programming? My book (Lawrenceville press C++) had them and they were quite annoying.

[@IAmESG]

How do i insert values inside the { }?

[@jesuscabrea]

how do you pass a 2 dimensional array to a function ?

[@invinciblegamer2796]

An amazing channel fr thank you so much🙏❤️

[@brianlaudrupchannel]

can you give an example of when you want to use a multi array?

[@willstalder4465]

+billyblackburn87 A checkerboard

[@bif7412]

Bucky! how do you put multidimensional arrays into a function

[@TimelessPiano]

This is where I got stuck in java at Multidimensional Arrays this time am pushing past this and moving on.

[@breenud39tv]

Hey, why when I try to do cout

[@Nahiyan12]

@JakobRobert00 I am not comparing GML to C++, GML is only suitable for games but there are a lot better languages for making games(I know that). I was just replying to another member, not comparing any language - just describing a language and explaining why it should not be compared with C++. It's not like a proper language, but much like giving commands to Game maker and tell it to give instructions to the computer in behalf of the user which is good for newbies. You misunderstood me.

[@GlamourDees94]

do you have a video on finding the median in a 2d array?

[@schellman2]

how do you create a multidimensional array that the user inputs the values? I have an issue with an assignment where I have float PlayerStat[10][3]; and I do not know how to allow the user to input their own values. The only libraries we have learned to use are and I keep finding all of these other examples with different code than I recognize. If anyone could help me out that would be great!

[@pushkarsoni8927]

+Eric Schell here's the program int array[10][10], r,c; cout

[@johnvincent7978]

[@pushkarsoni8927]

John Vincent so you want to add two matrix,,am i right? if not please tell me.. however i am posting the solution for the addition of two matrix

[@pushkarsoni8927]

+pushkar soni contact me if you have any other query or any questions on c++....my email.- [e-mail]

[@johnvincent7978]

i already got it thanks your video was really helpful

[@Som1Lse]

@olivebates Definitely easy to learn. The only problems with it is that it isn't as powerful as other programming languages (such as C++), nor is it completely free to use.

[@puffbluesam021]

WOW! JUST WOW! THANK YOU SO MUCH BUCKY!!!!

[@aiseknewton]

int R,C; scanf("%d %d",&R,&C"); char string1[ R] [C]; does this work? i want to make the row and col flexible as i input the R and C

[@togmeister8604]

Ahhh. It would be really cool if you did a tutorial on editing pngs. Then you could arrays and the random methods and have user enter a seed and dimensions then it would generate a image of set dimensions and have random noise in it.

[@khankingdom7969]

Can you please teach how to pass an array as a parameter

[@johnvincent7978]

sir how do you make them add every row and column #include using namespace std; int main() { int array[5][5],r,c; coutc; cout

[@ghostcheckblack]

Can you please make a 2 dimensional array for grading system? Name= prelim, midterm, semi final, final ? thanks.

[@TakingItCasual]

Why am I finding this so extremely easy to understand?

[@Orangejuice9000]

Just curious, but is it possible to create a multidimensional array containing two smaller arrays with different sizes? For example: sally[ ][ ] = { {1,2,3}, {10,11,12,13,14,15} } ???

[@karlsaba2681]

Orangejuice9000 yes of course

[@eshanimhatre]

It is possible

[@HarryAGeorgiou]

Hey @Bucky, I am sure I have more or less done something similar and should not have what I see, can you or others Ifigure out why I get a strange output when I want to display the whole array? #include "pch.h" #include using namespace std; int main() { int sally[2][3] = { {2,3,4}, {8,9,10} }; //rows.columns cout

unable to access your forum i.e. thenewboston.com/ .It says file not found.

[@urcousinveer]

Use 2 2D arrays also known as matrices as below. Matrix A - {2,3} Matrix B - [{1},{2}} Multiply these 2 matrices using nested for loops. I got this question in my programming exam but I could figure it out. Can you help me with this question please?😕

[@muhammadmashhoodsheikh1006]

[@exsertchillax]

Programming is actually very difficult to learn. I hate to read about programming and instead watching buckys tutorials, because it's so much simpler to learn it from him than boring books.

[@bloods212]

how can i use decimal numbers in arrays?

[@Kobortor]

Use the float or double instead of int. For example double a = 2.1;

[@devanshshukla8513]

Bucky, god bless you brother :)

[@gigahertzish]

could you make 3 or 4 dimensional arrays?

[@FrankLopezx]

is this how we go about building jacobian ? or matrix/matrices ?

[@saraesmayili]

Exactly

[@Nahiyan12]

@olivebates GML is really easy language but it is not for making powerful programs as there is no built-in function to make text boxes, drop downs, etc. However, it has built-in powerful functions for making really good games, even 3d games. So I think there is no point of comparing it with C++ or any other language used for making programs, Game maker language is a must for beginners but not for making big programs, just for making games. I love GML and you really don't need to code GUI, etc.

[@kathandesai9016]

Wait,what?There's a lot of confusion going on in my mind.Isn't this the opposite of COORDINATE System.There we consider our nos. with respect to X-axis whereas in C++d didn't they take nos with respect to X axis????

[@shockminerx1518]

In computer programming, (0,0) is started at the top left corner. Look up a picture of the computer coordinate system. It will make a lot more sense.

[@AndyU96]

There is no need at all to compare it to the coordinate system that we know, it's just a different version of it, I myself sometimes use different coordinate systems, like one that has the positive numbers on the left side and negatives on the right

[@MinoKubala]

You just need to rotate both x and y axes by -90° -─-┐ __.▼

[@Globox822]

I am sure it it comming in later videos, but what is practicle use of this?

[@dibbiepk]

If you wanted to make your own table or "database" for example, that was able to handle multiple users or information at once, and then you can draw information from multiple accounts or datasets at the same time. There are many uses for it, I dont know how common it is now, because most people would use SQL for that reason, but im sure there are many other uses as well. It really depends on what you might need a "table" for.

[@musakhan5927]

awesom work bucky

[@Boomerlance]

I cannot believe i actually understood this!!!!!!

[@sandy1995]

Is it possible to visualize an array with more than 3 dimensions?

[@iplay4us]

sandypet1995 hard but yes. you might search on google for it.. but get ready for pretty mindfucked stuff

[@sandy1995]

yeah that's what I am afraid of.

[@iplay4us]

but better check it out when you are more confident with programming. At the moment I cant really work more than 3d arrarys

[@ne0g3n3sis8]

sandypet1995 I wouldn't think so since humans are only capable of perceiving the world through a three-dimensional paradigm.
