Overloaded '+' operator adds two Measures

Demo Code

#include <iostream>
using namespace std;

{
   private:
       int feet;
       float inches;
   public:
       Measure() : feet(0), inches(0.0)
       {  }
       Measure(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 showdist() const
       { cout << feet << "\'-" << inches << '\"'; }
       Measure operator + ( Measure ) const;  //add 2 distances
};
//add this distance to d2
Measure Measure::operator + (Measure d2) const  //return sum
{
   int f = feet + d2.feet;
   float i = inches + d2.inches;
   if(i >= 12.0)                  //if total exceeds 12.0,
   {                           //then decrease inches
       i -= 12.0;                  //by 12.0 and
       f++;                        //increase feet by 1
   }
   return Measure(f,i);

int main()

    dist1.getdist();                //get dist1 from user
    Measure dist2(11, 6.25);       //define, initialize dist2
    dist3 = dist1 + dist2;          //single '+' operator
    dist4 = dist1 + dist2 + dist3;  //multiple '+' operators
    //display all lengths
    cout << "dist1 = ";  dist1.showdist(); cout << endl;
