Basic Loop Question.

Heya, guys. So I took a giant step back and decided to re-do the fundamentals of loops. I started with the While Loop. I made a successful code that asks the user to input two numbers, a Maximum number and a starting number.

Max = 50

Start = 1

The loop will add 1 each time until it reaches 50. :)

Now, what I want to do, is make it so that the starting number multiplies itself until it reaches the maximum number, but I have one small problem.

Here is the code:

#include <iostream>
using namespace std;

int main()
{
    int maxNumber;
    int startNumber;

    cout << "Hello, there!  Choose a maximum number for this loop, please." << endl;
    cin  >> maxNumber;

    cout << "Now, enter the starting number of the loop." << endl;
    cin  >> startNumber;

        while (startNumber != maxNumber){
            cout << startNumber * startNumber << endl;
            startNumber ++;
        }

    return 0;
}

So, I put 50 as the max number, and 2 as the starting number.

The output is this:

2
4
9
16
25
36
...
...
...
2209
2304
2401

Why is this? Thanks for the help.

Perhaps because startNumber never exactly equals maxNumber, so the loop never terminates? Try using greater than or less than instead of simple equality.

Right! I just thought of that. Okay, give me a couple of minutes. Haha, it just hit me! :P
