No output window

[marrom]

Hi I tried to run the hello world .cpp file, but no window is formed.
And I've tried system(pause), cin.get(); etc, and still nothing came out.
I doubt it's my computer's problem, does it matter that my system is window 10?

Here are the codes


// my first program in C++
#include <iostream>

int main()
{
std::cout << "Hello World!";
}

What compiler/IDE are you using? It does not matter that you have Windows 10. I use Visual Studio with Windows 10.

First press F9 to compile.
If that is successful, press F10 to run the program.
Also, if it will not run, it may be an antivirus problem. I think Avast has been known to cause problems.
