Buckys C++ Programming Tutorials - 58 - function Templates

[@kadenzxc]

Made it half way through the video without realizing your keyboard was upside down. I applaud you.

[@rubyPWNS1]

+Kaden Burgart It can't be real, right?

[@prayushkhadka6981]

how was he spacing?? makes you think

[@g38ra]

I think there's even someone's chuckling in the background @ 6:12 or was that the keyboard being flipped by him.

[@curious_sphinx]

What you should be applauding is his sense of humor!

[@JishKlur]

It is crazy watching this video now when i first started programming 4 years in my free time as a beginner. Now I am learning this in college and I happened to stumble upon one of buckys videos for help and it feels unreal that now I am actually doing this as a career.

[@MrR3set]

Josh Klauer You just described what will be me in just 4 weeks :) I learnt all this on 2015 but i forgot couple things i wanna sharp

[@johnmullin2963]

"Alright Bill, Let me be. I will do this."

[@TheVerbalAxiom]

"Oh it was upside down" *Facepalms* REALLY BUCKY? REALLY? Lmao

[@tige630]

Can't beat Bucky, this is the best cpp series I have ever seen, concise and straightforward every time.

[@jurakpreetsingh2155]

Hey ,can you code in c++?

[@Seyeumi]

oh my god the way you explained this was so perfect. This is the exact kind of approach I need when being taught coding, a more analytical approach. Thank you so much! This helped immensely 😇

[@karnkraftverk]

Thanks man, reading my book is useless, I never learn anything, but from these videos I understand it directly!

[@user-tz9kn1nu3u]

What books you were reading if I may know?

[@rarity7797]

Were you reading your book upside down like how Bucky was using his keyboard upside down?😂

[@tiygar8548]

@@rarity7797 xD

[@ikllnp]

You are the best C++ programming instructor ever. I wish you taught me back in school

[@jasontiller]

Thanks Bucky! I know this stuff takes time, so it's cool that you're doing this. Just a few things: 1. Bill Gates doesn't run Microsoft any more. 2. The compiler instantiates a new copy of addCrap for each time it's called with a different argument type. There is no polymorphism going on - templates are purely a compile-time facility.3. You can indeed add chars and strings together - anything that supplies an operator+ and a copy constructor will as addCrap arguments or any built-in type that supports addition will work.

[@ignitiondj4025]

WHAT HOW DID YOU WRITE EVERYTHING WITH YOUR KEYBOARD UPSIDE DOWN

[@raurus8202]

don't question bucky, underling

[@Sokar599]

Oh it was up side down :P lol

[@JackKirbyFan]

I SWEATED learning Templates because it was coated with layers of complexity. You broke it down to - oh -- that's it!!!! Wow! Best teacher OUT THERE!!!! WELL DONE!

[@sankhanilnayek9345]

Love that southern drawl man. Guns, barbecues and C++. Sounds like a blast.

[@maxfried5328]

Bucky is still saving college kids in 2022

[@khanhchanto3128]

Thank you Bucky, this is so useful. I was frustrating about this topic and when I google it, i just couldnt find a source that explains well. I own you one.

[@MrJapug]

Bucky after many months of struggling to understand templates, it finally made sense watching this video!!!! I have a cognitive disorder and this has been my biggest challenge when it comes to programming since I started studying this stuff! Thank you 🙏 so much! I love your tutorials btw!

[@bpmoran89]

Been watching you since my intro class. you rock!

[@raftingdon2]

damn, I wish I would have found you 3 months ago. I was attempting to write a template function and having issues and I found this. I really enjoy the way you describe the reasons for doing some of this stuff. It actually helps understand the concept. The book I have just describes what it is, and I leave myself wondering "Why in the world would you ever do that".

[@JoseGonzalez-rt5fk]

6:05 The moment when you are teaching someone a lesson, but you realized the lesson you're trying to tell is actually upside down.

[@gabrissk02]

Bucky, you probably have already figured out what you hit at 5:39, but anyways, for anyone who doesn't know... It's the debugger (hit the f8). While debugging, you can't close the terminal window

[@anteconfig5391]

"See that's what you guys get when you buy a new keyboard and all the keys are all over the place, I'm sorry this is like a keyboard... oh wait a minute! Oh it was upside down. ok it's fine now"

[@abhijeetckar]

i love the way bucky brings his compiler down from the corner to show us output.. like!! Surprise!!!

[@4Y0P]

Who's Jenna? :D

[@g38ra]

Yep, never heard of that as a variable before, she must be too special ;)

[@4Y0P]

W ALT Haha yeah, such a pretty name too

[@black_squall]

Slooty name

[@agnesakne4409]

some pretty girl he fucked

[@TheMusterionOfRock]

This standup show has a really good programming tutorial also

[@humzauddin6692]

"Oh it was upside down" Bucky I love you hahaha

[@jamshaidmushtaq1811]

One of the major parts of this video was Bucky's battle with his keyboard. XD

[@JokerzWyld]

This is life saving

[@alina_dial]

bucky is the coolest teacher ever

[@JigsaTopman]

God bless you Bucky!!!

[@ThunderLightStrikes]

This guy can be a great stand up comedian.

[@abdannour26]

Awesome :), you make it easy in the eye, keep up man. :)

[@andeluuledna]

Bucky is basically my savior

[@jordmax12]

lol nice tutorial but see you got a thing there for "jenna"? ;)

[@feilauren4166]

Jordan Max Bucky has too much personality to have to program a girlfriend.

[@jim0_o]

You should make a thumbs up script tutorial, I keep forgetting to thumb your videos up because my brain is full.

[@charlesajones77]

I have a degree in computer science (from 20 years ago) and I had no idea you could do this.

[@ulianazlotnik3093]

thank you!! love your simple explanations!

[@KW-dg6fs]

Imagine how much time would be saved if most professors/TAs are anywhere close to giving this good of an intro, then most of our time would be spend playing around with the codes, instead of beating ourselves up trying to understand what the fuck is the purpose of a template.

[@mohamedkhalilzouitni3803]

I salute you, bucky ! you're the man.

[@yoismak]

Bucky: Oh! the keyboard was upside down. me: *turns keyboard upside down*

[@nizamnovruzov5648]

I failed on my Programming exam but ,anyway thanks Bucky. Your videos helped me a lot.

[@xkilla911]

F

[@DeuceisLegit]

Dude, I wish I could subscribe to you 100 times.

[@crait]

Bucky is the Dunkey of programming.

[@dbthem]

5:42 this is why I use Mac 😄 Btw, great series, thank you!

[@ThatDamnYouth]

What program were you using/compiling in? Awesome vid

[@Trazor]

awsome tutorial... meanwhile, how to make the template functions expect (take in) different type of data?? what is that way?? is there any tutorial where you have described that method ( way ) ??

[@ditz3nfitness]

We’re right about using “typename” instead of “class” in the gives the same result, right? VS ?

[@avarussurava9488]

Thanks for the tuto but I got a question for anyone reading this, if the template function gives us such an advantage of not having to define a function type, why are functions still relevant then ?

[@xxgamerwormxx2809]

You could even use the add() function and pass in objects that use operator overloading.

[@xkilla911]

funny how you realized your keyboard was upside-down half-way but how were you typing with an upside-down keyboard for the first half of the video? did you learn how to type upside-down in your keyboarding class?

[@satheeshbrcm]

thanks for the tutorial.. Nicely explained !

[@folksgames7047]

Exactly what I needed thanks!

[@FaizanZahidNustian]

U give superb examples !

[@TEKFROLOGIC]

Question. So even with the template, wouldn't you still have to copy/paste it to make different functions and change to signs (ex. change the + to -)?

[@EmanBook]

Hi Bucky , Could you please tell me which program you're using to record your videos ?? BTW , You really helped me with your videos ...YOU'RE A W E S O M E

[@Impulse_Photography]

He is using CODE BLOCKS ...

[@ditz3nfitness]

What would happen if you decided using characters instead of numbers? Would it return the character added together into a word, or what would happen?

[@trannelish9]

i love it.. clear and quick

[@adnanmunawar7972]

Bucky you are awesome! You rock!

[@MarcosFerreira-rc1me]

I keep on having this problem whenever i add two numbers together, it gives me "4293399" :?

[@SealOSRS]

What's your code?

[@asfadasfa1234]

ive been wondering how to do this for about 8 months.. thanks man.

[@joaopinto4422]

taipadada taipadada taipadada taipadada taipadada taipadada taipadada taipadada

[@bovery23]

I've never heard the word DA-------TA so many times!!!!

[@TheFlyguy31]

Excellent as always..

[@Jack-4242]

@joaoris yes he did watch tutorial 5: How to build a basic calculator there he uses "cin"

[@TheKiloOhm]

I understand what the template function does but if it's so great why people even bother using all the different types of data? Does this take up more memory?

[@browncoffee12]

Now a have a perfect calculator, without overloading lot's functions just like bucky mentioned haha

[@avengerbolt4908]

Hi your tutorials are very good. I need to print system id(mac address) for this which module I need to use ? Or can you make a tutorial on that?

[@alphaahtube]

That's why they made the reply feature, so we don't have to look for @lilsabaa reply.

[@gabrielreinfalke2277]

nice video, bucky!

[@VersusDec]

Liked on 43 second for addCrap :DDD

[@Matthmatt1213]

Bucky: So awesome he codes upside-down.

[@addobandre99]

What if I want to restrict the types of data that are being used (for example: Inputing strings will mess up everything)?

[@mirsahib596]

i just fell from my chair when he say 'oh wait the keyboard is upside down'

[@ujjvalpatel5353]

I have one doubt, what if I assign Bucky as int ,just as you did;and then I call another function "multiplycrap" working with double. I am unable to do so, compiler argues bucky was not declared in this scope for second call ?? plz anyone reply..

[@YTHandle660]

Maybe its the coding order

[@splinter1817]

i did kind of same thing , Actually bucky can be replaced with only one data type at a time . So Bucky cannot play a role of both double and int at the same time.

[@OskarNendes]

But everyone forgets that cout knows how to handle generic types of data. How should I do if I want to create the new c-out?

[@NeostormXLMAX]

7:25 wow its like you read my mind i was just about to ask that lol

[@rodney8018]

lmfao same, i was about to open code blocks till he said that.

[@gatraw]

well wait, what if I have both int and doubles and I want it to switch between the two based on user input?

[@edgardrodriguezruiz]

Great stuff keep the good job

[@reemaljaber]

alright guys welcome back to your fjdfgjghfj c++ tutorial " stuck in my head XDDD

[@mohamedtark7014]

ريم الجابر are u a software engineer?

[@reemaljaber]

لا :/

[@mohamedtark7014]

يعنى انت شاطرة فى السى بلس بلس ولا لسه بتتعلمى زى حلاتى كده؟

[@reemaljaber]

لسه اتعلم 😹:)

[@mohamedtark7014]

ربنا يوفقك

[@atata0215]

what about define the template funktion like that : template const int& max(const int&,const int&); can you explain ?

[@zerozano]

What constitutes as a "general" data type. I'm trying to use the template for string and user defined class data types but I can't, for whatever reason. I have used both class and typename for the template but none of those work. I'm not even sure what the differences are honestly.

[@WhatsACreel]

+zerozano There's no difference between “typename” and “class”. You can use classes and strings, but only if they specify the operators that you use in the template. For instance, the string class specifies the “

[@JoseGonzalez-rt5fk]

3:12 Yeah, and that way is by using the type, "auto".

[@JoseGonzalez-rt5fk]

I don't really see the difference from using function templates and using the type, "auto".

[@786suhaib786]

auto cannot be used inside a parameter list.

[@JoseGonzalez-rt5fk]

khansuhaib Any examples?

[@786suhaib786]

I may have misunderstood you but you are proposing that instead of using templates we can do something like auto add(auto a, auto b) { return a + b; } This will give a compiler error because while defining the parameters, in this case a & b we cannot use the keyword auto. If you want why is this so, it is because when we define something as auto it has to have a resolution at compile time, but since functions are dispatched at run time auto doesn't get resolved at compile time thus giving an error.

[@JoseGonzalez-rt5fk]

khansuhaib This actually works completley fine. Using auto is just like declaring a int or something. Although it would throw an error if you put a int value and a double which the error would be that you cannot add a int and a double. I would obviously only use auto if I did not know what it would give out just to make my job easier. I heard that one of the uses for templates was to find what a pointer's address was addressing to (as in finding the address of what the pointer pointed at kind of like finding the address of x even when you are using the y's pointer to x). I probably won't need this until probably I would (which would not probably be anytime soon). I would learn this when I need to is what I'm saying. I don't find much of a use for it as of now.

[@marcinszymanek3894]

I will definitely remember that when my boss, Bill Gates, asks me to write a function that adds crap.

[@MaxGuides]

Great, *but* how do I pass another function through my template?

[@Impulse_Photography]

Do using Function Templates eliminate Function Overloading ?

[@MegasXLR]

I prefer to type it as "template " as I may get confused if I type 'class' :)

[@javiermarin4298]

gtakros it's for the sake of simplicity of the video.

[@WilliamGLewis-yt9fw]

what compiler is being used? I'm new to C++ and don't know what compilers are most accessible to new coders

[@steam_vortex2608]

You should try Visual Studio Community version; it's free and it's an awesome IDE with built in compiler; it also is diverse in that it can code in numerous languages depending on what types of programs you are typing to make (it can use C#, C, C++, Python, Javascript and several other languages as a default which you can choose from when initializing a file type). Just remember that when you are making additional files that communicate with one another they have to be saved in the same folder; I'm also somewhat new to coding by the way. I've been practicing for about 3-4 months and it's finally starting to make sense; in any case, good luck with your learning. Cheers!

[@YouKnowMeDuh]

For future reference, I know of the Cygwin g++ and MinGW g++ compilers, which can be used with Netbeans if you wish.

[@blazingkin]

Good job mr upside-down keyboard man

[@alexisperez4581]

Does anyone know what program he's using? I like the simple interface.

[@TheGamesOfGaming]

Code Blocks 99% sure :) Tutorial 1 was installing Code Blocks I use VS doe

[@waisaleratulevu6315]

Alexis Perez you should try using Netbeans. Its awesome

[@feilauren4166]

Alexis Perez Simple editors - Code Blocks, Sublime, Brackets, all good with very simple interfaces.

[@BigSeeProduction]

Fei Lauren Atom and CLion are great too!

[@feilauren4166]

Nice. Always checking out new things.

[@dibbiepk]

Well, it depends on the datatype, if its a string, and a int, then you would have to make it accept for that, id say re-watch his video over, and replace what he sais with what u want, like instead of 26 + 14, do somthing like a + b, if it doesnt work, its not like you lost anything, PM me, and ill try to get you more detail if you need it

[@joshuapierson801]

In a sense he is right you can learn basic techniques but, in the long run you are either a programmer or a coder a programmer can write almost anything using a language . A coder is someone who knows a programming language but can only write things like cout and cin. Not knowing about file streams or string functions. So in a since you can be a beginner but in that you would be a coder not a programmer.

[@mananbarjatya1822]

what if we want to do the same thing in "main" i mean like if we make a program where the user enters an anonymous data type..

[@herp_derpingson]

Apparently I cant add a int to a double. Looks like C++ doesnt support Coercion. e_e

[@dresnyd]

6:10 "Oo wait a minute, Ooh, it was upside down!" please tell me you were not referring to the keyboard :D

[@wojtushom1741]

What IDE do you use?

[@DuckSleazzy]

have you ever tried square root of 4 and then -2 in windows calculator... and also sqrt(9) and then -3...??? :) ;)

[@alexanderleeart]

so this is like dynamic typing in Python?

[@Tulanir1]

1:52 "And make sure we don't have any errors, and we have 50..."

[@Fieldy6654]

awesome tut, beautifeel-

[@srarun1996]

shouldn't i get 'c' as output if i pass char 'a' and 'b' as parameter? :P no seriously. why not char?

[@ethendixon4612]

Alright, Bill . . . Let me be . . . I will do this!! 😂

[@YTHandle660]

Is this the same a void * functionName (Generic Pointer)
