Question

Provide code and full projects neatly and in proper form and in the correct header and cpp files((we have to make 3 files header file , one .cpp file for function and one more main cpp file)

Operator Overloading – Chapter 14

1. Design a class Complex for representing complex numbers and the write overloaded operators for adding, subtracting, multiplying and dividing 2 complex numbers. Also create a function that will print a complex number on the screen. Provide appropriate constructors and destructor.

Over load the operators + (add), - (minus), * (multiply), = , != (comparison), and provide the operators << and >> to printout and read in respectively. See section 14.9 of Liang C++ textbook for help with some operators.

Answer 1

#include<iostream>
#include<stdlib.h>

using namespace std;
//body of complex class
class complex
{
int real;
int img;
public:
complex() //default constructor initialize the members to 0
{
real=0; img=0;
}
//parameterized constructor will initialize the members by users given values
complex(int r,int i)
{
real=r;
img=i;
}
//>> operator overloading to input
friend istream & operator >>(istream &p,complex &k)
{
cout<<endl<<"Enter the real and imaginary part of a complex number";
cin>>k.real>>k.img;
return p;
}
//<< operator overloading for output
friend ostream & operator<<(ostream &p,complex &k)
{
p<<k.real <<" +i "<<k.img;
return p;
}
//+ operator overloading to add two complex numbers
complex operator +(complex c);
//- operator overloading for subtraction
complex operator -(complex c);
//* operator overloading for multiplication
complex operator *(complex c);
// '/' operator overloading for division
complex operator /(complex c);
// != operator overloading
bool operator !=(complex c);

// = operator overloading
void operator =(complex c);

};

//!= operator overloading. It will return true if both the omplex numbers are unequal otherwise false.

{

// ' /' operator overloading

//driver program
