What is your code? What exactly is the issue?

[Hacker4life]

printf("Hello world");
?

[CodeTiger]

or std::cout << "Hello world" << std::endl; ?

Lemme guess, the window pops up then disappears too quickly to see. You could add std::cin >> x; to just let it stay open expecting input, run without debugging if using visual studio, or set a break point and run it, and various other ways.

Or run it from the terminal.

Why are using

printf("HELLO WORLD");

that is a code for the language C not C++

In C++ you would do it like this:

cout<<"HELLO WORLD";

In C++ you would do it like this:

Why can't you use it in c++ ?

[neil@crunchbang ~/chceck/cb]$ vi printf.cpp
[neil@crunchbang ~/chceck/cb]$ g++ -o a.out printf.cpp
[neil@crunchbang ~/chceck/cb]$ ./a.out
Are you sure we can't use it in c++?
[neil@crunchbang ~/chceck/cb]$

here's the code

#include <stdio.h>

int main()
{
printf ("Are you sure we can't use it in c++?\n");
return 0;
}

C++ is an extension of C. Do not forget that.

Just to put some fuel on the fire, the reason to use printf instead of cout is that printf is actually faster. Not by much, but it is.

Plus I'm guessing this thread is solved... Anyone feel like closing it?
