What is Overloading in C++ ?

C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively.

 
 

Function overloading : :

You can have multiple definitions for the same function name in the same scope. The definition of the function must differ from each other by the types and/or the number of arguments in the argument list. You can not overload function declarations that differ only by return type.

Operators overloading : :

You can redefine or overload most of the built-in operators available in C++. Thus a programmer can use operators with user-defined types as well.

Overloaded operators are functions with special names the keyword operator followed by the symbol for the operator being defined. Like any other function, an overloaded operator has a return type and a parameter list.

 

Below is the source code for C++ Program to Compare Two Strings using Overloading which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C++ Program to Compare Two Strings using Overloading  */

#include<iostream>
#include<stdio.h>
#include<string.h>
using namespace std;

class String
{
        char str[20];
        public:

          void getdata()
        {
             gets(str);

        }

         int operator ==(String s)
        {
               if(!strcmp(str,s.str))
                return 1;

                return 0;
        }
};

int main()
{
        String s1,s2;

        cout<<"Enter first string :: ";
        s1.getdata();
        cout<<"\nEnter second string :: ";
        s2.getdata();
        if(s1==s2)
        {
            cout<<"\nStrigs are Equal\n";
        }
        else
        {
            cout<<"\nStrings are Not Equal\n";
        }
        
        return 0;
}

OUTPUT : :

/*  C++ Program to Compare Two Strings using Overloading  */

Enter first string :: CodezClub

Enter second string :: codezclub

Strings are Not Equal

Process returned 0

Above is the source code and output for C++ Program to Compare Two Strings using Overloading which is successfully compiled and run on Windows System to produce desired output.
