Question

I am trying to write a piece of code that will take the number let’s say 24 and get all the factors for it so it would print the numbers 1 and 24, 8 and 3, etc. I tried doing this myself however I am fairly new to using c++ so it kind of confuses me a little. I apologize if this is really easy or simple to answer. could you please show me how this could be done?

int y = 0;
int x = 0;
int product = x * y;

while (true)
{
    product = x * y;
    x++;
    y++;
    if (product == 24)
    {
        cout << x << " " << y << endl;
    }
}

that is the code I tried doing it with but I realized that since x and y are increasing at the same time it will never reach 24 as a product.

Answer 1

Rather than y++, try y = 24 / x. Just start x at 1, not zero!

So:

x++;               // do this first, so x isn't zero
y = 24 / x;       // get closest y, rounding down
product = x * y; // see if it works
if (product == 24)
