Question

Chapter 14 starting out with c++ from control structures through objects

Feet Inches Modification Modify the FeetInches class discussed in this chapter so it overloads the following operators: <= >= != Demonstrate the class's capabilities in a simple program.

Answer 1

source code:

#include<iostream>
using namespace std;
//clas dist
class dist
{
private:
int feet;
float inches;
  
public:
dist():feet(0),inches(0){}
  
dist(int f, float in): feet(f),inches(in){}
  
void getdist()
{
cout<<"feet=";
cin>>feet;
cout<<"inches=";
cin>>inches;
}
  
friend bool operator <=(dist d1, dist d2);// <= operator overloading
friend bool operator >=(dist d1, dist d2);// >=operator overloading
friend bool operator !=(dist d1, dist d2);// != operator overloading
  
};

bool operator <=(dist d1,dist d2)
{

float dd1=d1.feet+d1.inches/12;
float dd2=d2.feet+d2.inches/12;
return dd1<=dd2?true:false;
}

bool operator >=(dist d1,dist d2)
{

float dd1=d1.feet+d1.inches/12;
float dd2=d2.feet+d2.inches/12;
return dd1>=dd2?true:false;
}

bool operator !=(dist d1,dist d2)
{

float dd1=d1.feet+d1.inches/12;
float dd2=d2.feet+d2.inches/12;
return dd1!=dd2?true:false;
}

int main()
{
dist d1(7,6.56);
dist d2;
d2.getdist();
if(d1<=d2)
cout<<"d1 is smaller than d2"<<endl;
if(d1>=d2)
cout<<"d1 is greater than d2"<<endl;
if(d1!=d2)
cout<<"both d1 and d2 are not equal"<<endl;
return 0;
}

output:
