C++ static_cast Converts a length in yards as a decimal value to yards, feet, and inches.

#include <iostream>

  unsigned int inches {};              // Whole inches

  std::cout << "Enter a length in yards as a decimal:  ";
  std::cin >> length;

  // Get the length as yards, feet, and inches
  yards = static_cast<unsigned int>(length);

                       (length*feet_per_yard *inches_per_foot) % inches_per_foot;
