@lyric quail It'll make more sense as you learn more of the language.

#include <iostream> includes declarations for standard library i/o utilities

[lyric quail]

can you tell me whit an example?

[tacit kayak]

And every C++ program must have an int main() {}, that's where your program starts running

[tacit kayak]

If you want to use std::cout or std::cin, you must #include <iostream>

okay

@tacit kayakint is use for integer?

[tacit kayak]

Yep

[lyric quail]

so

the

code is telling the main is an integer and the inside of it is also integer?

im correct?

and std :: cout<< is a print command?

like

python

[tacit kayak]

main is a function which returns an integer

though unlike other functions you're allowed to omit the return in main (it defaults to returning zero)

[tacit kayak]

yep

[lyric quail]

okay

if i don't put return 0; what will happend?

[tacit kayak]

in main you are allowed to omit the return 0;, it's a special case in the language

[lyric quail]

Okay

[jaunty swift]

Only in main

any other function you must return correctly

(i.e specifically main returning 0 is the special case)

[lyric quail]

do you have any tip for me i am beginner? @jaunty swift @tacit kayak
