C program to multiply two complex no?

Answer 1

/*C++ program to multiply two complex numbers using * operator overloading*/

#include<iostream.h>

#include<conio.h>

class complex

{

float x,y;

public:

complex() {}

complex(float real,float img)

{

x=real; y=img;

}

complex operator*(complex);

void display()

{

cout<<x<<" + "<<y<<"i"<<endl;

}

};

complex complex::operator*(complex e)

{

complex temp;

temp.x=x*e.x+y*e.y*(-1);

temp.y=x*e.y+y*e.x;

return(temp);

}

void main()

{

clrscr();

complex c1(5,3),c2(3,2),c3=c1*c2;

c1.display();

c2.display();

cout<<"Multiplication"<<endl;

c3.display();

getch();

}

OUTPUT:

5 + 3i

3 + 2i

Multiplication

9 + 19i
