    The source code is

    #include <iostream>
    #include <conio.h>

    int main()
    {
    cout << "Hello World\n";
    getch();
    }

    I use gcc, and it outputs to a.exe if you don't specify an output name. I don't know how your compiler does it, but it may have generated a default executable. check your directory.

    also, while namespace is customary and good programming practice,
    Code:
    using namespace std;
    doesn't really do anything (it defaults to std namespace). It won't fix any compile errors.

    hmm

    Try putting a 'return 0;' before the closing bracket, I'm not sure if this will help though... We're there even any errors?

    You have your main() function of type int, yet it doesn't return anything? Do what Da-Spit said and change your code to
    Code:
    #include <iostream> 
    #include <conio.h> 
    
    int main() 
    { 
    cout << "Hello World\n"; 
    getch(); 
    
    return 0;
    }

    I'm an old school programmer, and I dont normally use namespace std; through habit, but I always use #include<iostream.h> rather than #include<iostream>, I've seen <iostream> where using namespace std; is used but never without, so maybe that's the problem. I don't have a compiler here though so I cant check it. Looking back at the compiler output though it seems to get to the linking stage, so I dont think this will have anything to do with it.
