Find Largest of Two Numbers

Problem Statement

Write a program to find the largest of two numbers entered by the user.

This is a very common beginner-level programming problem and is frequently asked in coding interviews and exams.

Logic Explanation

Take two numbers as input from the user
Compare both numbers
If the first number is greater, print it
Otherwise, print the second number

Algorithm

Start
Read two numbers a and b
If a > b, print a as the largest
Else, print b as the largest
Stop

#include <stdio.h>

int main() {
    int a, b;
    printf("Enter two numbers: ");
    scanf("%d %d", &a, &b);

    if (a > b)
        printf("Largest number is %d", a);
    else
        printf("Largest number is %d", b);

    return 0;
}

#include <iostream>
using namespace std;

int main() {
    int a, b;
    cout << "Enter two numbers: ";
    cin >> a >> b;

    if (a > b)
        cout << "Largest number is " << a;
    else
        cout << "Largest number is " << b;

    return 0;
}

import java.util.Scanner;

class LargestNumber {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter two numbers: ");
        int a = sc.nextInt();
        int b = sc.nextInt();

        if (a > b)
            System.out.println("Largest number is " + a);
        else
            System.out.println("Largest number is " + b);
    }
}

Python Program

a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

if a > b:
    print("Largest number is", a)
else:
    print("Largest number is", b)

Input

15
10

Output

Largest number is 15

Important Notes

This program uses if-else condition
Works for positive and negative numbers
Forms the base for solving largest of three numbers

Interview Tip

“Finding the largest number is often used to test your understanding of conditions and comparison operators.”

Conclusion

In this program, we learned how to compare two numbers and find the largest one using simple logic.
This problem helps beginners understand decision-making statements like if-else, which are very important in programming.
