The house thing you said really helped me understand formatting so much better. You have taught me more than this stupid college class.

[@yellowhellow-wi9gi]

you explained it so goood ı've never understand the functions this well thank you

[@FrederikWollert]

I really like your C++ series. Keep it up. Please make more C++ Videos. So, let's defeat the RUclips algorithm.

[@KapeelManek]

tip from papa please use using namespace std;

Its a bad practice in professional environment

I'm not a professional, but I will try to explain it as well as I can.
Writing "using namespace std" is considered a bad practice, because it makes it more likely for a name clash to happen.
If you are writing a small program, something like "Hello world" then using "using namespace std" is fine, but the problem arises with bigger projects.
Let's say we got a statement "std::cout

[@dvxv4016]

@@mhmdhusseini4864 i heard that way you force every dependent file to use the same namespace

[@HabiburRahman-mm2su]

@@mhmdhusseini4864 It’s because there can be other custom namespaces as well. While in case of learning,
" using namespace std:" is okey, but "std::" makes working easier for others coders, as well as not forcing them to scroll from bottom to top for modification.

int mass ;
double weight ;
std::cout mass;
std::cout

[@memezilla2964]

what is void?

[@Ctrl-Z-Renders]

no return type (does not give anything back)

[@Anonymous-st1vk]

if you write int in place of void, it means the function return integer when executed (like the main function), void means it a funtion that doesn't return anything, other datatypes can also be put here

[@AdrielBryanCherian]

@@Anonymous-st1vk which means that in order to stop a function that has a int in place of void.. you would have to return 0;?

[@fakemand]

@AdrielBryanCherian In order to stop it you have to return int, it doesnt have to be 0, but yes it can be

[@Yourcodingfriend9999]

Ok soo to create a function in c and c++
we can use void but it will return nothing and you can use data types like int, double they will return something but only the function's data type

[@taigo5766]

finally, hello world v2.0
#include
void hello(std::string world);
int main()
{
std::string world = "Hello, World!";
hello(world);
return 0;
}
void hello(std::string world)
