Question

Write a C++ program to overload ‘+’ operator to find the sum of length of two given strings.(Note: if S1 and S2 are two strings then S1+S2 should give the sum of lengths of S1 and S2).

Answer 1

Answer:

A C++ program to overload ‘+’ operator to find the sum of length of two given strings.

Explanation:

// C++ Program to concatenate two string  

// using unary operator overloading  

#include <iostream>  

#include <string.h>  

using namespace std;  

// Class to implement operator overloading  

// function for concatenating the strings  

class AddString {  

public:  

   // Classes object of string  

   char s1[25], s2[25];  

 

   // Parametrized Constructor  

   AddString(char str1[], char str2[])  

   {  

       // Initialize the string to class object  

       strcpy(this->s1, str1);  

       strcpy(this->s2, str2);  

   }  

 

   // Overload Operator + to concat the string  

   void operator+()  

   {  

       cout << "\nConcatenation: " << strcat(s1, s2);  

   }  

};  

 

// Driver Code  

int main()  

{  

   // Declaring two strings  

   char str1[] = "Hello";  

   char str2[] = "Shivam";  

   // Declaring and initializing the class  

   // with above two strings  

   AddString a1(str1, str2);  

 

   // Call operator function  

   +a1;  

   return 0;  

}

Output:-

Concatenation: HelloShivam

Length: 11
