```#include<stdio.h>
void main()
{
int a1,a2,b1,b2,m1,m2,m3,m4,d,r1,s;
float r,r2,x,y;
a1=5; b1=2; a2=7;b2=-4;d=0;s=0;
//Multiplication of complex number
m1=a1*a2;
m2=b1*(-(b2));
m3=a1*b2;
m4=a2*b1;
int m5=(m1+m2);
int m6=m3+m4;
if(m6>0)
printf("
Multiplication of complex num: %d+%di",m5,m6);
else
printf("
Multiplication of complex num: %d %di",m5,m6);
//Division of complex number
d=(a2*a2) +(b2*b2);
if(m6>0)
printf("
Division of complex num: (%d+%di)/%d",m5,m6,d);
else
printf("
Division of complex num: (%d %di)/%d",m5,m6,d);
//Squareroot of complex number
r1=(5*5)+(2*2);
r=sqrt(r1);
r2=(r-a1)/2;
y=sqrt(r2);
x=b1/(2*y);
printf("
Square Root(1): %f +%fi",x,y);
printf("
Square Root(2):-%f -%fi",x,y);
}```
