Write a C program for multiplication of two complex numbers?

Answer 1

Answer:

#include<stdio.h>

#include<conio.h>

main()

{

int a,b,i=1,c1,c2,m;

clrscr();

printf("\nENTER THE VALUE OF a,b:");

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

c1=a+i*b;

c2=a-i*b;

printf("\n");

pritnf("\nTHE COMPLEX NUMBERS ARE:");

printf("\n);

printf("a+ib=%d\ta-ib=%d",c1,c2);

m=c1*c2;

m=(a*a)+(b*b);

printf("\n");

printf("\nTHE MUL OF TWO COMPLEX NUMBERS IS=%d",m);

getch();

}

Answer:

z.real = x.real*y.real - x.imag*y.imag;

z.imag = x.real*y.imag + x.imag*y.real;
