Write the definition for a class called complex that has flo

Write the definition for a class called complex that has floating point data members for storing real and imaginary parts. The class has the following member function: void disp() to display complex number object Define a constructor to set the values of the objects. Write main function to create five complex number objects. Set the value in two objects using constructor & Use Operator overloading to find sum, difference and product of the complex numbers and return in the 3^rd, 4^th & 5^th object respectively. Display all complex numbers.

Solution

Here is the solution:

#include <iostream>
using namespace std;
#include<string.h>
#include<stdio.h>
class complex
{
float i,r;
public:
complex(){}
complex( float real, float imag )
{
      r=real;
      i=imag;

}
void disp()
{
cout<<r<<\"+\"<<i<<\"i\"<<endl;
}
complex operator+(complex a2)
{
complex a;
a.r=r+a2.r;
a.i=i+a2.i;
return a;
}
complex operator-(complex a2)
{
complex a;
a.r=r-a2.r;
a.i=i-a2.i;
return a;
}
complex operator*(complex a2)
{
complex a;
a.r=(r*a2.r)-(i*a2.i);
a.i=(r*a2.i)+(i*a2.r);
return a;
}
};
int main()
{
   complex c1=complex(10.05,6.00);
   c1.disp();
   complex c2=complex(10.00,9.00);
   c2.disp();
   complex c3,c4,c5;
   c3=c1+c2;
   c3.disp();
   c4=c1-c2;
   c4.disp();
   c5=c1*c2;
   c5.disp();
}

Output:

10.05+6i

10+9i

20.05+15i

0.05+-3i

46.5+150.45i
