Aim: To implement a program to add two polar coordinates using operator overloading.

Code:                      

#define PI 3.14

class polar

{

            double theta;

            double r;

            public:

            void getdata();

            void display();

            double convert(double);

            double revert(double);

            polar operator+(polar p2);

};

void polar::display()

{

            double t;

            cout<

}

double polar::convert(double t)

{

            double x;

            x=(PI/180)*t;

            return(x);

}

double polar::revert(double t)

{

            double x;

            x=(180*t)/PI;

            return (x);

}

void polar::getdata()

{

            double t;

            cout<<"Enter value of 'r':";

            cin>>r;

            cout<<"Enter value of 'é':";

            cin>>theta;

}

polar polar::operator+(polar p2)

{

   polar p3;

   double x,y,t1,t2,t;

   t1=convert(theta);

   t2=convert(p2.theta);

   x=(r*cos(t1))+(p2.r*(cos(t2)));

   y=(r*sin(t1))+(p2.r*(sin(t2)));

   t=atan(y/x);

   p3.theta=revert(t);

   p3.r=sqrt((x*x)+(y*y));

   return(p3);

}

void main()

{

            polar p1,p2,p3;

            clrscr();

            p1.getdata();

            p2.getdata();

            cout<

            p1.display();

            cout<<"\nB:";

            p2.display();

            p3=p1+p2;

            cout<<"\n\nAfter addition:\n\nA + B = ";

            p3.display();

            getch();

}

Output:

Enter value of 'r':1

Enter value of 'Θ':45

Enter value of 'r':1

Enter value of 'Θ':45

A:1 cos 45° + 1 sin 45°

B:1 cos 45° + 1 sin 45°

After addition:

A + B = 2 cos 45° + 2 sin 45°
