Operator Overloading

[sameena]

Hi

Doing a course in C++.Net which upto now has been ok and interesting. However Operator Overloading is confusing me to a great deal. There is plenty written on the subject but for Computer Scientists who just love mathematics and complicated text! To find something simple – it does not exist. I can use operator overloading like a parrot but I want to know what exactly is going on…how does the compiler treat an overloaded operator…etc.

We were asked to make an Exponent class that will allow us to overload the ^ operator so that we can perform exponential notation so that you can have iResult=iNumber ^10 where iNumber equals 10 so that iResult equals 1000. This is my zillionth attempt but the overloaded function is not called..please help.

This is the class:

#pragma once

#include 

#include 

using namespace std;

class Exponentor

{

public:

    Exponentor(void);

    ~Exponentor(void);

    //Exponentor operator ^ (int num1);

    //Exponentor operator ^ (Exponentor&);

    Exponentor operator^(int num1);

    int iLeftNum;

    int iRightNum;

    int iResult; // no private vars required...

};

This is the code:

#include "exponentor.h"



Exponentor::Exponentor(void)

{

iResult=0;

iLeftNum=0;

iRightNum=0;

}



Exponentor::~Exponentor(void)

{

}



void main() {

    Exponentor Exponent;

    cout << "Welcome to Exponentor the exponent test programme!n";

    cout << "**************************************************n";

    int iRightNumber;

    cout << "Hello, please give me the left operand:";

    cin >> iRightNumber;

    cout << "nand now please give me the right operand:";

    int iAnyNumber;

    cin >> iAnyNumber;

    Exponent.iResult=iRightNumber ^ iAnyNumber;

    cout << "nThe result of  " <<

Exponent.iLeftNum << " raised to " << iAnyNumber << "

is:" << Exponent.iResult << endl;



    }

//Exponentor operator^(int num1);

Exponentor Exponentor::operator^(int num1)

{

    cout << "In the function";



    return *this;

}

Thanks in advance
