im using cplusplus. co m to learn how to code
but im doing the hello world thing
but i dont understand what the iostream file really does for the program
and also does 'using namespace std" allow you to name things in your program?

[whit++]

iostream provides input and output functionality using streams

And no std is a namespace inside iostream thats allows you to use cout, cin and much more

well #include <iostream> basically makes it so you can use cout, cin, and more(if you dont know what that is your gunna have some trouble making hello world). iostream is included in most c++ programs.

The real code to use cout is actually:

std::cout<<"blah blah"<<endl; (or something)

what using namespace std; does is make it so you don't need to include std::.

the above code simplifies to:

cout<<"blah blah"<<endl;

not the best explanation but that's all you need to know for now :}

goodluck.


edit: goddamnit whit beat me.
