Answer to Question #181886 in C++ for VARUN

Question

Compile time polymorphism using operator overloading

Create a class Distance with feet and inches. Write an overloaded function to copy the value of one distance object into another distance object using = operator overloading.

Answer 1

#include <iostream>


using namespace std;




class Distance
{
  int _feet;
  float _inches;




  public:


      int GetFeet()
      {
          return _feet;
      }




      float GetInches()
      {
          return _inches;
      }




      void SetFeet(int feet)
      {
          _feet = feet;
      }




      void SetInches(float inches)
      {
          _inches = inches;
      }




      Distance()
      {
          _feet = 0;
          _inches = 0;
      }




      Distance(int feet, float inches)
      {
          _feet = feet;
          _inches = inches;
      }




      Distance(const Distance &distance)
      {
          _feet = distance._feet;
          _inches = distance._inches;
      }


      Distance& operator=(Distance &distance)
      {
          _feet = distance.GetFeet();
          _inches = distance.GetInches();
          return *this;
      }
};




int main()
{
    Distance d1, d2;
    cout << "Before assigning: feet = " << d2.GetFeet() << ", inches = " << d2.GetInches() << endl;
    d1.SetFeet(10);
    d1.SetInches(20.0);
    d2 = d1;
    cout << "After assigning: feet = " << d2.GetFeet() << ", inches = " << d2.GetInches() << endl;
    return 0;
}
