Class Programming

Create a class 'COMPLEX' to hold a complex number. Write a friend function to add two complex numbers. Write a main function to add two COMPLEX objects.

Program Code:

#include<iostream.h>

#include<conio.h>

class complex

{

float real,imag;

public: void get_complex();

void show_complex();

friend complex add_complex(complex c1,complex c2);

};

void complex::get_complex()

{

cout<<"Enter real number :";

cin>> real;

cout<<"Enter Imaginary number :";

cin>>imag;

}

void complex::show_complex()

{

cout<<real<<"+i"<<imag;

}

complex add_complex(complex c1,complex c2)

{

complex c;

c.real=c1.real+c2.real;

c.imag=c1.imag+c2.imag;

return c;

}

int main()

{

clrscr();

complex c1,c2,c3;

c1.get_complex();

c2.get_complex();

c3=add_complex(c1,c2);

cout<<"\nComplex Number 1 = ";

c1.show_complex();

cout<<"\nComplex Number 2 = ";

c2.show_complex();

cout<<"\nSum of Complex Number 1 and 2 = ";

c3.show_complex();

getch();

return 0;

}

Output of the above program is:

Enter real number :12

Enter Imaginary number :10

Enter real number :3

Enter Imaginary number :5

Complex Number 1 = 12+i10

Complex Number 2 = 3+i5

Sum of Complex Number 1 and 2 = 15+i15
