Answer to Question #173786 in C++ for Rocky bhai

Question

Create the class Complex that has floating point data members for storing real and imaginary parts and perform complex number addition. The class Complex has the following member functions: Complex() - Null constructor invokes when an object is created Complex(float, float) - Parameterized constructor to set the specified value of real and imaginary parts in object friend complex sum(complex, complex) - Friend function to perform complex number addition and return complex number display() - Function to display complex number object

Answer 1

#include <iostream>
class Complex
{
public:
	float real{0};
	float imaginary{0};
	Complex() {}
    Complex(float r, float i) :real(r), imaginary(i)
	{}
	void display() {
		if (imaginary>=0)
		std::cout << real << "+" << imaginary << "i"<<std::endl;
		else std::cout << real  << imaginary << "i" << std::endl;
	}
	friend Complex sum(Complex c, Complex d);
	
	


};
Complex sum(Complex c, Complex d) {
	Complex result;
	result.real = c.real + d.real;
	result.imaginary = c.imaginary + d.imaginary;
	return result;
}
int main()
{
	//example work ;
	Complex z1(10, 35), z2(8, -97), z3;
	z3 = sum(z1, z2);
	z3.display();
	return 0;
}
