Practical-24

Write a cpp program for implementation of mathematical operations on strings.. {overloads two operators + and <=}​

Introduction

Code​

Practical-24.cpp
#include <iostream>
#include <string>
#include <algorithm>

using namespace std;

// Function to overload + operator
string operator+(const string& s1, const string& s2)
{
    // Concatenate two strings
    string s = s1 + s2;

    // Return the concatenated string
    return s;
}

// Function to overload <= operator
bool operator<=(const string& s1, const string& s2) {

    // Compare two strings
    int result = s1.compare(s2);

    // If s1 is smaller than s2
    if (result <= 0) {
        return 1;
    }

    // If s2 is smaller than s1
    else {
        return 0;
    }
}

// Main function
void main()
{
    // Declare two strings
    string s1 = "Naruto";
    string s2 = "Itachi";

    // Concatenate the strings
    string s3 = s1 + s2;

    // Print the concatenated string
    cout << s3 << endl;

    // Compare the strings
    bool result = (s1 <= s2);

    // Print the comparison result
    cout << result;

    return 0;
}

Output​

NarutoItachis
