Question

I know I am probably just doing something dumb wrong, but I need to take a number from the user, create an infinite loop (by making my while statement true) of multiples of 2. I got the math to multiply the number from the user times itself, but I can’t get it to loop. This is the last part of my homework for the week and my brain is fried, so I can’t figure out where I went wrong!

Any help would be amazing! Here is what I have:

#include <iostream>

using namespace std;

int main (int argc, const char * argv[])
{
    int d;
    int e;
    cin >> d;
    while (true)
    {
        e = d * d;
    }
        cout << e << ", ";
}

Answer 1

There is unreachable code at: cout << e << ", ";
Perhaps this was meant to go in the while loop?

You are assigning e the value of d*d over and over. Because d*d does not change, the value of e never changes. Perhaps you should initialize e to the number you want outside of the loop, and then set e = e * 2 inside of the loop, then print e. This will print multiples of your number by successive powers of 2, which is what I think you want.
