Sample C Program To Add Two Complex Numbers.

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>

struct complex
{

int real;
int img;

};

int main()
{

struct complex a, b, c;
printf(" Enter a and b where a + ib is the first complex number. ");
printf(" \na = ");
scanf(" %d ", &a.real);

printf(" b = ");
scanf(" %d ", &a.img);

printf(" Enter c and d where c + id is the second complex number. ");
printf(" \nc = ");
scanf(" %d ", &b.real);

printf(" d = ");
scanf(" %d ", &b.img);

c.real = a.real + b.real;
c.img = a.img + b.img;

if ( c.img >= 0 )
printf(" Sum of two complex numbers = %d + %di ", c.real, c.img);
else
printf(" Sum of two complex numbers = %d %di ", c.real, c.img);

getch();
return 0;
}

OUTPUT:

Enter a and b where a + ib is the first complex number.
a = 6
b = 2
Enter c and d where c + id is the second complex number.
c = 2
d = 6
Sum of two complex numbers = 8 + 8i
