Write the definition for a class called complex that has floating point data members for storing real and imaginary parts. The class has the following member functions:
void set(float, float) to set the specified value in object
void disp() to display complex number object
complex sum(complex) to sum two complex numbers & return complex number

#include<iostream.h>
#include<conio.h>


class complex
{
   private:
 float x;
 float y;
   public:
 void set(float real, float img)
 {
  x=real; y=img;
 }
 complex sum(complex);
 void disp();
};

complex complex::sum(complex C)
{
 complex t;
 t.x = x + C.x;
 t.y = y + C.y;
 return t;
}

void complex::disp()
{
 cout<<x<<" + j"<<y<<endl;
}


int main()
{
 complex C1,C2,C3;

 C1.set(2.5,7.1);
 C2.set(4.2,5.5);
 C3=C1.sum(C2);

 cout<<"\n complex Number 1 = ";C1.disp();
 cout<<"\n complex Number 2 = ";C2.disp();
 cout<<"\n complex Number 3 = ";C3.disp();

 getch();
 return 0;
