7) Write a C++ program that implements () operator for calculating Distance in feet's and inches.

 #include<iostream>

using namespace std;

class Distance

{

private:

int feet,inches;

public:

Distance()

{

feet=0;inches=0;

}

Distance(int f,int i)

{

feet = f;

inches = i;

}

Distance operator ()(int M)

{

Distance D;

D.feet=M*3.25;

D.inches=M*40;

return D;

}

void display()

{

cout<<"Feet : "<<feet<<" Inches :"<<inches<<endl;

}

};

int main()

{

Distance d1,d2(11,10),d3;

cout<<" Constructor 1 for Distance "<< endl;

d1.display();

cout<<" Constructor 2 for Distance "<< endl;

d2.display();

cout<<"operator () to convert meter into feets and inches"<<endl;

d3=d2(20);

d3.display();

return 0;

}

output:

 Constructor 1 for Distance 

Feet : 0 Inches :0

 Constructor 2 for Distance 

Feet : 11 Inches :10

operator () to convert meter into feet's and inches

Feet : 65 Inches :800
