a silly question

Dear GCC team,

I am really a newcomer, so I am wondering how to compile this source
code in the attachment.

Regards,

#include <iostream>

int main ()
{
    int sum = 0, val = 1;
    while (val <= 10)
    {
       sum += val;
       ++val;
    }
    std::cout << "Sum of 1 to 10 inclusive is " << sum 
    << std::endl;

    return 0;
}
