Program to check if a rectangle is a square or not

Given the dimensions of a rectangle (length and breadth), write a program to determine whether the given rectangle is a square or not.

Examples:

Input: Length = 5, Breadth = 5
Output: Square
Explanation: Since the length and breadth of the rectangle is same, therefore the given rectangle is a square.

Input: Length = 6, Breadth = 8
Output: Rectangle
Explanation: Since the length and breadth are different, therefore it is a rectangle.

Approach: To solve the problem, follow the below idea:

If the length and breadth of a rectangle are equal, it is a square. Otherwise, it is a rectangle.

Step-by-step algorithm:

• Take the input for length and breadth.
• Check if length equals breadth.
• If true, print “Square.” Otherwise, print “Not a Square.”

Below is the implementation of the algorithm:

C++

#include <iostream>
using namespace std;

int main() {
    int length, breadth;
    // Example test case
    length = 5;
    breadth = 5;

    if (length == breadth)
        cout << "Square" << endl;
    else
        cout << "Not a Square" << endl;

    return 0;
}

C

#include <stdio.h>

int main() {
    int length, breadth;
    // Example test case
    length = 5;
    breadth = 5;

    if (length == breadth)
        printf("Square.\n");
    else
        printf("Not a Square.\n");

    return 0;
}

Java

public class SquareChecker {
    public static void main(String[] args) {
        // Example test case
        int length = 5;
        int breadth = 5;

        if (length == breadth)
            System.out.println("Square.");
        else
            System.out.println("Not a Square.");
    }
}

Python3

# Example test case
length, breadth = 5, 5

if length == breadth:
    print("Square.")
else:
    print("Not a Square.")

C#

using System;

class Program {
    static void Main() {
        // Example test case
        int length = 5;
        int breadth = 5;

        if (length == breadth)
            Console.WriteLine("Square.");
        else
            Console.WriteLine("Not a Square.");
    }
}

Javascript

// Example test case
let length = 5;
let breadth = 5;

if (length === breadth)
    console.log("Square.");
else
    console.log("Not a Square.");

Output

Square
