For Example

    #include <iostream>

    using namespace std;

    int main ()
    {
        int startNumber; //Initialize as an integer.
        int counter; //Initialize with a value of 0.
        int result = 0; //Initialize with a value of 0.
        const int endNumber = 5000; //Initialize with a constant value of 5000.

        //Ask the user for a number to use for calculations and store that in
        //the startNumber variable.
        cout << "Please enter a starting number: ";
        cin >> startNumber;

        //While result is less than endNumber, keep adding startNumber to it.
        //Keep track of the counter so that we can determine how many times
        //we had to loop through before the condition was met.
        for (counter = 0; result < endNumber; counter++)
        {
            result = result + startNumber;
        }

        //Return the end result
        cout << "It took " << startNumber << " added to itself " << counter << " times before it was greater than or equal to " << endNumber << "\n";
        cout << "The end value was: " << result;

        //Send an exit code (or error level) of 0.
        return 0;
    }
