C++ Program: While loop counter

Compiler (Visual Studio) showing C++ Source Code:

// While loop.
#include <iostream>
using namespace std;
int main()
{
   int num = 1;  // Initialize counter starting at 1.

   while (num <= 7) // Loop - number controls how many times.
   {
	 cout << num;  // Show the number as it increments.
   	 num++;  // Increment by adding 1 each iteration.
   	 cout << " - Hello world!\n";
   }
   cout << "\n";
   return 0;
