Answer 1

#include <iostream>

using namespace std;

int main() {
    int feet, inches;
    cout << "Enter number of feet: ";
    cin >> feet;
    while (feet < 0) {
        cout << "Number of feet is negative. Please enter number of feet: ";
        cin >> feet;
    }
    cout << "Enter number of inches: ";
    cin >> inches;
    while (inches < 0) {
        cout << "Number of inches is negative. Please enter number of inches: ";
        cin >> inches;
    }

    double centimeters = (feet*12 + inches)*2.54;

    cout << "Number of centimeters = " << centimeters << endl;
    return 0;
}
