Answer to Question #240495 in C++ for siri

Question

WAP to declare a class which stores a complex number. Include a member function which compares the modulus of the two complex class objects and returns the object with higher value. Include a parameterized constructor which arguments with same name as that of the class data members. 

Answer 1

#include <iostream>
using namespace std;


class Complex{


private:
	double real,imag;


public:
	Complex(){
		this->real=this->imag=0;
	}
	
	Complex(double r, double i){
		this->real=r;
		this->imag=i;
	}
	
	Complex(Complex &obj){
		this->real=obj.real;
		this->imag=obj.imag;
	}
	
	int compare(Complex &obj){
		double modulusThis=sqrt(this->real*this->real+this->imag*this->imag);
		double modulusOther=sqrt(obj.real*obj.real+obj.imag*obj.imag);
		if(modulusThis>modulusOther){
			return 1;
		}
		if(modulusThis<modulusOther){
			return -1;
		}
		return 0;
	}


	void print(){
		cout<<real<<"+"<<imag<<"i"<<endl<<endl;
	}
	
	double getReal() const{
		return real;
	}
	
	double getImag() const{
		return imag;
	}
	void setReal(double re){
		real = re;


	}
	void setImag(double im){
		imag = im;
	}
};


int main()
{
	double real1,imag1,real2,imag2;


	cout<<"Enter the Real part of First Number: ";
	cin>>real1;
	cout<<"Enter the imaginary part of First Number: ";
	cin>>imag1;
	Complex obj1(real1,imag1);
	obj1.print();


	cout<<"Enter the Real part of Second Number: ";
	cin>>real2;
	cout<<"Enter the Imaginary part of second number: ";
	cin>>imag2;
	Complex obj2(real2,imag2);
	obj2.print();




	if(obj1.compare(obj2)==1){
		cout<<"The Complex 1 is bigger than Complex 2\n";
	}
	if(obj1.compare(obj2)==-1){
		cout<<"The Complex 2 is bigger than Complex 1\n";
	}
	if(obj1.compare(obj2)==0){
		cout<<"The Complex 2 is equal Complex 1\n";
	}




	cin>>imag1;
	return 0;
}
