## Multiply complex numbers:

Given two complex numbers 2 + 3i , & 3 + i The result of multiplication is

(2 + 3i) (3 + i )= 6 + 2i + 9i + 3i2

since i2 = -1

=> 6 + 11i - 3 =3 + 11i

Write a C program to find multiplication of two complex numbers / Write a C program to multiply two complex numbers

#include<stdio.h>

int main(){

int a,b,c,d,x,y;

printf("\nEnter the first number:");

scanf("%d%d",&a,&b);

printf("\nEnter the second number:");

scanf("%d%d",&c,&d);

x=|( a * c ) - ( b * d )|;

y= ( a * d ) + ( b * c );

printf("\n The result is %d + %d i :", x, y);

}

OUTPUT:

Enter the first number:2 3

Enter the second number: 5 2

The result is : 4 + 19i
