Thread: Need help...

What exactly are the problems that you are facing with the code that you have written?

A lot of people on here are not happy to follow links.

You should post your code with code tags like this:

Code:

#include <stdio.h>

    while(response == 'Y' || response == 'y'); /*The do-while statement inside int main() is used to ask if the user wants to run the program again (see function getResponse)*/
    
    return 0;
}

Rewrite your code in testable way. For example:

Code:

float getHeight(const float ft, const float in)
{
    return 0.3048 * ft + 0.0254 * in;
}
