AIM:
A program to perform simple arithmetic operations of two complex numbers using operator overloading.

ALGORITHAM:

• Start the process
• Get the complex value a.real and a.image
• Check while ((ch=getchar())!=’q’)
o True : execute switch(ch)
o Case ‘a’:Then
Compute c<-a+b, Print c.real and c.imag o Case ‘s’: Then Compute c<-a-b, Print c.real and c.imag o Case ‘m’: Then Compute c<-a*b, Print c.real and c.imag o Case ‘d’: Then Compute c<-a/b, Print c.real and c.imag o End of switch • End of while • Stop the process PROGRAM

complex operator -(struct complex a, struct complex b)
{

c.real=a.real-b.real;
c.imag=a.imag-b.imag;
return(c);
}
complex operator *(struct complex a, struct complex b)
{
complex c;
c.real=((a.real*b.real)-(a.imag*b.imag));
c.imag=((a.real*b.imag)+(a.imag*b.real));
return(c);
}
complex operator +(struct complex a,struct complex b)
{
complex c;
c.real=a.real+b.real;
c.imag=a.imag+b.imag;
return(c);
}
complex operator /(struct complex a, struct complex b)
{
complex c;
float temp;
temp=((b.real*b.real)+(b.imag*b.imag));
c.real=((a.real*b.real)+(a.imag*b.imag))/temp;
  		 return(c);
}

OUTPUT

Enter the first complex no: 1,1
Enter the second complex no: 2,2

Addition of 2 no’s : 3+I3
