Demo Code

#include <iostream>
using namespace std;

{
   int feet;/* w ww .  j a  v a2 s .c o  m*/

};

void engldisp(Measure);
int main()
{
   Measure d1, d2, d3;
   //get length d1 from user
   cout << "\nEnter feet: ";  cin >> d1.feet;
   cout << "Enter inches: ";  cin >> d1.inches;
   //get length d2 from user
   cout << "\nEnter feet: ";  cin >> d2.feet;
   cout << "Enter inches: ";  cin >> d2.inches;
   d3 = bigengl(d1, d2);        //d3 is larger of d1 and d2
   //display all lengths
   cout << "\nd1="; engldisp(d1);
   cout << "\nd2="; engldisp(d2);
   cout << "\nlargest is "; engldisp(d3); cout << endl;
   return 0;
}
// compares two structures of type Measure, returns the larger
Measure bigengl( Measure dd1, Measure dd2 )
{
   if(dd1.feet > dd2.feet)      //if feet are different, return
      return dd1;               //the one with the largest feet
   if(dd1.feet < dd2.feet)
      return dd2;
   if(dd1.inches > dd2.inches)  //if inches are different,
      return dd1;               //return one with largest
   else                         //inches, or dd2 if equal
      return dd2;
}
// display structure of type Measure in feet and inches
void engldisp( Measure dd )
