Ok this is what I have so far. I believe this is correct, but how do I find the number of yards, feet and inches in the user input? Any clue?

#include <iostream.h>

using namespace std;

int main()
ofstream outfile;
const double conversion = 2.54;
double centimeters;
double inches;


cout << "Enter length in centimeters: ";
cin >> centimeters;
cout << endl;
cout << "The number entered was " << centimeters
<< " for centimeters. " << endl;

centimeters = inches * conversion;
