Write a code to overloading the comparison operators (== and != ).In this code compaison of complex number.

 

The comparison operator are all binary operator , mainly if you are doing comparison operator output is mainly bool.

	#include<iostream>
	using namespace std;
	//Class definition
	class complx
	{
	private:
	int real;
	int imag;
	public:
	complx(){}
	complx(int a,int b)
	{
	real=a;
	imag=b;
	}
	friend bool operator ==(complx &n1,complx &n2);// == operator overload
	friend bool operator !=(complx &n1,complx &n2); // Not equal operator overload
	void print()
	{
	cout<<real<<"+"<<imag<<"i"<<endl;
	}
	};
	bool operator ==(complx & n1,complx &n2)
	{
	return (n1.real==n2.real && n1.imag ==n2.imag);
	}
	bool operator !=(complx & n1,complx &n2)
	{
	return (n1.real!=n2.real || n1.imag !=n2.imag);
	}
	int main()
	{
	complx c1(1,2),c2(1,2);
	c1.print();
	c2.print();
	complx c3(1,2),c4(4,2);
	if(c1==c2)
	{
	cout<<"Both complex number is equal "<<endl;
	}
	c3.print();
	c4.print();
	if(c3!=c4)
	{
	cout<<"Both numbe is not equal "<<endl;
	}
	return 0;
	}

1+2i
1+2i
Both complex number is equal 
1+2i
4+2i
Both numbe is not equal
