Learn C++ With Me #9 - Arrays

Welcome back to the C++ for beginners tutorial series! This video will cover arrays! An array is a way to store multiple elements in the same variable, and they are extremely important to know how to use when coding. We'll create arrays, see the different types of arrays, distinguish between an array and a list, and more.

Dude you are the only person that I don't skip the adds so that I support you.

[@typeterson8376]

I feel the need to say it each video, but I do appreciate these videos. You are a good man

[@DatNguyen-vj1ro]

Your content is really good for beginners who want to learn C++. I know C++ but could not teach it as well as you do

[@lowpolygons8562]

You have no idea how much i needed this thank you so much

[@YarosMallorca]

I always thought that C++ is hard! But with your tutorials and prior C and Python experience it's not that hard as I thought! Thanks for making these tutorials!

[@antonyanchev7112]

Make a long one for pointers and references please

[@ArshdeepSingh42108]

This was really an awesome and detailed lecture 🙌

[@funkuwest5967]

Thank you... these videos are really helpful !!

[@neontuts5637]

Nice video Tim. Small tip - you can execute the c++ code inside the sublime text by creating a build system for it. Which will automatically compile and run the code.

[@alexander_0749]

hey can u plz tell me the build code? mine's not accepting any input

[@michaelsilvers1260]

@@alexander_0749 Yeah the build code is system.run(visual studio.exe). Lmao joking. I know ur comment is 3 years old, but thought I'd have some fun. No need to compile these days, eh?

thanks tim

[@Samcpfc]

I'm really curious as to why when you assign the size of your array to 'x' that it doesn't throw you an error about the array needing to be a constant value.

[@sanduchicu7545]

Heyy. Can you please make a video about json reading and writing & parsing tutorial.

[@tcgvsocg1458]

Can you create a video recorder in python but from scratch without module

[@kimeg7294]

Hi, is it possible to assign an integer value, greater than 2^32-1, as element of an array of integer type?

[@damnstupidoldidiot8776]

Use longs or long longs.

[@agneaybnair9519]

Hey Sir, can you create a tutorial on PyCairo

[@abrarmasumabir3809]

plz make a video on Vim and it' s plugins

[@gravesucheoma2416]

I think the word that you are looking for is implicate, or Implicitly define the size. Although, I guess you could say that "we can defer the size of the array to the complier" or something like that, which would mean the same thing technically. Sorry, haha!

[@aaravgp1332]

are you going to cover vectors and stl?

[@yourdadsbestfriend7101]

patience young one

Hi tim is just idea but can you do a intermediate tutorials of Javascript maybe? its just idea

[@LittleRapGuy]

chillin

[@Sultan4Mc]

Is this text editor sublimeText

[@softwhere07]

interesting. But I can't wait until you do something with "while statements" and "for loops". that is if you do. I mean those are pretty important aren't they? I hope you do.

[@blackpeppercinnamon3244]

Hello Tim thanks for this series. Can you do a video on the iomanip class. That would be really helpful

[@blackpeppercinnamon3244]

@Peterolen that's what I meant. Been studying classes so I have them in my head. Thanks for the clarification

Hey Tim can u pls make a video on socket in detail i have seen ur video on socket they are not clear. can u pls make anothet

[@ikbenmathijs9424]

Why doens't the size it takes in byte it gives from sizeof() change between a string that's only 2 characters and a string that's 10 million characters that makes the entire file more than 16 megabytes in size???

[@user-sy3ny1sz2w]

String is stored in memory aka RAM not in the actual file LOL

[@ikbenmathijs9424]

@Peterolen Thanks, that makes sense

[@thanhtupham4726]

I will follow your series till pointer part :V

[@soggycarrot3319]

I have a question What if I want to create an array of 1 - 200 but dont want to manually type the number?

[@storytimewithgreg]

You could use loops to append to the array.

[@soggycarrot3319]

lol I already figured it out list[200]; for ( i = 1; i

[@siamahmed8287]

Hey tim. Please make a series on python algorithms

[@joaomelo6011]

Are you going to do a serie for developing backend with c++ ?

[@andreaspatounis5674]

13:07 are this numbers always the same?

[@segsfault]

No it's random, because when you don't initialise the values of any array of any variable, c++ gives it a random value and then stores it in the RAM because you can't store anything empty inside the RAM

[@andreaspatounis5674]

@@segsfault thanks for answering my question

[@trafon31]

5:04 that's a bad practice and not "completely valid". In the compilation phase, while allocating memory for variables X does not have an assigned value, so you cannot create an undefined sized array. This will lead to crashes when you are using older/low level C/C++ compilers (lets say you are working on 8086 systems). Do not use this. Defining your array size as MACRO is the way to go. However if you are using never versions of C++ compiler, this will be handled automatically, but will lead to performance loss.

[@anonymologist7946]

Thanks a lot! I encountered the issue you mentioned. I was trying to figure out why, but didn't find any helpful info until now. I am not sure what you mean by defining array size as macro? Could you explain more to me? Thanks!

[@jo-zw9eu]

why dont you use visual studio?

[@jo-zw9eu]

@Madhavaraj s oh ok tnx

[@kprubinaath9797]

[@kprubinaath9797]

@Peterolen oh thank you. learned a lot from you

[@shr1han]

g++ -Wall -o executable.exe code.cpp This would give you a warning about not returning from main (I guess)

[@random7983]

that's pretty sad, you're presenting the C syntax and not the C++ syntax which requires the header , not showing how to program in modern C++ in 2021 isn't that good unfortunately. :/

[@random7983]

@Peterolen what do you mean by regular exactly?

[@raffayirfan]

hello

[@SanjuKumar-ye8xz]

Second view

[@eamongas]

int x = 5; int arr[x]; is incorrect isn't it.

[@KoichiNakayamada]

Yeah, I think we need to make the size constant. const int x = 5; int arr[x] = {2, 3, 4, 5, 6};

[@samalocpp]

Bro couldn't even teach std::array, C-like array decaying to pointers when passed as a function argument, or that you can't return a C-like array from a function, just update yourself before teaching stuff to beginners

[@rishabhsemwal4180]

21 minute long video and total waste content. Just talking about errors. Instead you should have talked about methods and function of array

[@damnstupidoldidiot8776]

You cannot use a variable as the length of an array, that is a GNU extension. The length of an array must be a constant expression. You can get the length with .size if you use std::array.
