LAB 5:
In this lab we will focus on operator overloading in Classes.
Example 1: write C++ program to create class called distance, that
contains data members of feet and inches . The class have two constructors,
one to set values, and another to assign values , function to enter values
from user, function to display values, and function to find the summation
of distances.
#include <iostream>
using namespace std;
class Distance //English Distance class
private:
int feet;
float inches;
public:
Distance() : feet(0), inches(0.0)
{ } //constructor (two args)
Distance(int ft, float in) : feet(ft), inches(in)
{}
void getdist() //get length from user
cout <<"nEnter feet: ";
cin >> feet;
cout << "Enter inches: ";
cin >> inches;
void showdistO
cout << feet << "'-" << inches << *""<<endl;
Distance operator + (Distance d2) //return sum
int f = feet + d2.feet; //add the feet
float i = inches + d2.inches; /ladd the inches
if(i >= 12.0) //if total exceeds 12.0,
{
i- 12.0;
ft: //increase feet by 1
return Distance(f,i); //initialized to sum

int main()
Distance distl, dist3, dist4; /define distances
dist1.getdist(); /lget distl from user
Distance dist2(11, 6.25); //define, initialize dist2
dist3 = dist1 + dist2; //single *+' operator
dist4 = distl + dist2 + dist3; //multiple +' operators
I/display all lengths
cout << "distl = ":
dist1.showdist():
cout << "dist2 = ":
dist2.showdist(O;
cout << "dist3 = ":
dist3.showdist();
cout << "dist4 = ";
dist4.showdist();
return 0;
