Question

Create a class for working with complex numbers. Only 2 private float members are needed, the real part of the complex number and the imaginary part of the complex number. The following methods should be in your class: a. A default constructor that uses default arguments in case no initializers are included in the main. b. Add two complex numbers and store the sum. c. Subtract two complex numbers and store the difference. d. Multiply two complex numbers and store the product. e. Print a complex number in the form a + bi or a - bi where a is the real part of the complex number and b is the imaginary part of the complex number. f Change a complex number to its square. Your main should instantiate two complex numbers and call each of the class methods. The two complex numbers should be printed along with the sum, difference, and product of the two complex numbers. Lastly, print the squares of the two complex numbers. (Please do not overload the operators for this program.)

#include <iostream>
using namespace std;

class Complex
{
private:
float real;
float imag;

public:

void setComplex(void)

cout << "Enter the real and imaginary parts : ";
cin >> this->real;
cin >> this->imag;
}
Complex add(const Complex& c)

Complex comp;
comp.real = this->real + c.real;
comp.imag = this->imag + c.imag;
return comp;
}
Complex subtract(const Complex& c)
{
Complex comp;
comp.real = this->real - c.real;
comp.imag = this->imag - c.imag;

Complex multiply(const Complex&c)
{
Complex comp;

void square()
{
float temp=this->real;
this->real=this->real*this->real-this->imag*this->imag;
this->imag=2*this->imag*temp;
}
void printComplex(void)

cout << "Complex number after operation: " << this->real << " + " << this->imag << "i"<<endl;
else

int main()

/* Adding two complex numbers */

/* Subtracting two complex numbers */

/* Multiplication two complex numbers */

e.printComplex();

/*change the complex number to its square*/
cout << "Changing complex number a to its square: " << endl;
a.square();
a.printComplex();
}
