Buckys C++ Programming Tutorials - 9 - Functions

[@SomeIrishLad]

I am learning more from these videos than a whole year in college.

[@veljkovujovic9026]

Colin Maher me too xD

[@doruk6459]

Gaming _TV I like programming but I don't know which to choose from, either Computer Science or Computer Engineer or anything but I want to focus on Programming thanks for your help! :D

[@leonidas14775]

Doruk Gez CE requires lots of extra math, and seemingly irrelevant science classes. CS focuses mostly on programming and algorithms, but your school will probably make you take some advanced math regardless.

[@doruk6459]

YankeeSpirit Thanks, since it has more programming I will choose CS! :D

[@cutekurdish5388]

Colin Maher me too lol

[@FuryOutlaw]

We had an hour long lecture about this and you taught me this in 9 mins. College sucks man. Thanks sensei!

[@padoharaja4503]

fuck college

[@juliobecerra849]

🤣

[@TheSpiritBolt]

He taught me what void was in 15 seconds when high school couldn't teach me it in 3 years....

[@deletinqq6058]

I still haven't learnt it :

[@TheSpiritBolt]

basically its a function that runs, but the function is set to a "void" function because it doesn't return a value. where as if it was an int function it would return a number. you can do this for all kinds of variables

[@razmuzen1090]

[@yusufmahan7121]

hahahhaa the same

[@BrewmasterDonegan]

same for me...

[@LyingPrauses]

"my function, I can do what I want" nice one.

[@slayy7609]

Funny how an actual book that I'm reading doesn't explain this very well, but Bucky explains everything perfectly and I can actually understand.

[@shubhamrana3918]

Slayy SRSLY BROTHER NOW M FEELING MY C++ BOOKS ARE IRRELEVANT LOL !!! ,,,,, I HAVE GAIN 2 TIMES BETTER KNOWLEDGE FROM THESE VIDEOS INSTEAD FROM THOSE BOOKS .....BUCKY ROCKS !!!!! :D

[@ryu________]

Slayy I know how that feels. I paid a hefty amount for a book (our prof required us to) and here I am, watching his videos. lol

[@ScibbieGames]

+Slayy It took me 10 of his Java Tutorial Video's to actually understand java better than my friend LOL. And he was buzy for 2 weeks. I was buzy for 2 days

[@Ace-gw4uk]

+Shubham rana because you are reading books that require higher programming knowledge.

"Basically the job of a function is to do something..." Subscribes immediately

[@thavrisco1632]

IAmMig You subbed for the simplicity or because he's stating the obvious

[@Moon_Rose달장미]

omg, i loved these two things, especially: 1. when he was like , iostream, i know what this is, then using namespace, i know what that is too, then main, oh i know that too. then, printsomething. what the heck, i never seen that before,lol..... 2. later on u're gonna come acroos something called printSomething. now, we don't want u to freak out like u have before, sending us a whole bunch of error messages. i'm seriously like whoa, this guy's sense of humor is awesome, man!

[@BradenBest]

Hey you. Yes you, person watching this video. I'm going to teach you something that will help you better understand the inner workings of C++. When Bucky says "printSomething is used before it is defined", he doesn't mean it literally. It can't be "used" if main() isn't actually running. And the perfect evidence to debunk it is that if you provide a function prototype for printSomething() that appears before main, then it will work just fine. void printSomething(); int main(){ ... } void printSomething(){ ... } It's not defined yet, but now the compiler knows it exists. This is called a forward declaration. Its purpose is to announce the existence of a symbol without needing to define it. This specific type of declaration, with respect to a function, is called a function prototype. Bucky mentions this at 7:18 Symbol refers to an entity in the code that has a name, such as variables and functions. Now here's what happens during compilation: since C++'s type system is static, the first thing the compiler does is a phase called static analysis (SA). In this phase, the compiler reads the code and checks all of the symbols, references to symbols, and their types to make sure everything makes sense. This phase is not actually necessary for compilation. It is a tool provided by the language that makes use of the type system, to aid the programmer in minimizing human error. You could technically compile code without performing SA, but doing that would be irresponsible. So, the compiler sees the symbol "printSomething" during SA, and does not recognize it. Rather than go on a witch hunt for a symbol that may or may not exist, it just prints out an error and either aborts or continues the compilation (depends on the compiler). Most compilers will continue until the end of SA and then abort, so that the programmer is given a full list of errors and warnings. On the other hand, dynamic langs like JavaScript tend to go through with the aforementioned witch hunt, and have developed clever ways of making the lookup as efficient as possible. After SA, a symbol table is put together and stored along with several sections like .rodata (read-only data), .text (machine code), or .bss (uninitialized data). This information comes together in the form of an object file. For a more detailed overview, see this article, table w.3

[@BradenBest]

***** You're welcome. Just keep in mind that some of the information I gave, particularly that about the ELF binary format (.rodata, .bss, .text, .symtab, etc), is specific to systems that use ELF in their executables. Namely, Linux.

[@Bilanoo]

I am really new in these environment as I started this tutorial a week ago. Your comment made me understand better how C++ works. Thank you so much man :D

[@avy2602]

i've got an assignment to return in 1 week that should include functions. I've look all over the internet, you're the best. You saved me!! thanks :D (am new to to c++ :3)

[@abbbee8918]

I am completely new to programming and trying to understand the use of functions, and this made the complete sense. Extremely clearly presented. Thank you.

[@jlirving]

Thanks dude, I just needed some refreshing you broke it down really nicely! Looking to continue the series! I came here for help with Constructors (tutorial 14) but I decided to refresh functions.

[@wynterune]

I am SO glad I watched this video even if I already knew most of it. Prototyping is AWESOME!!! I have literally had to be SO mindful of function order before that I was dying inside and had main at the bottom constantly so that it could reach everything! Thank you so much for explaining this in intuitive terms as well! It was super easy to understand.

you are awesome dude. I can understand your tutorials easily.

[@BIGB185]

I'm taking a course called Program Design and Development online at my local community college. It's basically just C++. Both the text and instructor are confusing but these videos have helped me understand more than both of those two combined. Thank you and keep up the good work.

youre the reason im passing my exams... MUCH LOVE!

I know this is an old video but I just wanted to let you know that you are saving my life. I am majoring in Computer Science and am taking my first class and it is C++, everything was easy until we got to functions and pass by reference. My head was about to explode until I came across your video. Thanks!

Yes!!! I remembered watching this series when I tried to teach myself C++ at the age of 12. I didn’t get that much further than hello world from what I remember haha, but I am 24 now and work as an engineer. I think back to this series as one of my first inspirations into the computery STEM area, thanks so much for creating this! 😁

[@Lolatyou332]

So far c++ looks pretty similar to javascript

[@hollohead4077]

Ked Viper Java is to Javascript what Car is to Carpet. A stolen copy and paste quote that, but it gets the point across well enough that their first four letters are the only thing that relates them.

[@KeenanWoodall]

Yeah, I know JavaScript from within the Unity engine quite well and I agree. I'm surprised that its making sense so quickly! :) Bucky is a pretty great tutorial guy though, so that can't hurt!

[@DannysMyNanny]

Yes its very similar to JavaScript. I find c# to be more similar to java though.

[@willhughes5583]

Firstly, JavaScript and Java are two different languages, Java is an OOP Language whereas JavaScript is a web-scripting language. DO NOT get them mixed up. JavaScript is derived from C, and the syntax between these languages are similar due to that connection. Just REMEMBER Java and JavaScript are not the same.

[@maxwellhenrydiaba3080]

I love you guy because you just made the understanding of function very very easy to me as a beginner of C++.Keep it up Bucky.

Awesome. I studied C++ around 13 years and never managed to understand a single bit of it. Now I work in different field and don't use any programming etc, since I don't have to. But your videos enticed me to learn C++ again, as I find it much more interesting and engaging than my instructor told us. Thanks !!

when i first heard of c++ i thought it was going to be complicated for no reason but you Bucky have showed me it is nothing to fear and for that I thank you.

[@jasonarmani2056]

It helps the programmer or anyone else who looks at the code see what the function returns or accepts as parameters. Since most programs are written by teams it makes it helpful to see what your program needs to take and what it needs to return.

This if fckin good. Given that this tutorial is made 11 years ago. Massive game changer. Thanks a lot.

After 3 years, how'd it go?

[@SacredWasteMC]

Functions are very easy to understand. Take a look at the main function. That is the starting function, your computer calls that. All the other functions are called by the main function, or even other functions. If its void, it just does whatever is in the function. Boolean, String, and int functions return a Boolean, String, or int respectively.
