Kotlin: Find Remainder of Two Numbers

1. Introduction

In this blog post, we'll walk through a simple Kotlin program that computes the remainder when one number is divided by another.

2. Program Overview

Our Kotlin program will achieve the following:

1. Prompt the user to input two numbers.

2. Fetch the provided numbers.

3. Compute the remainder when the first number is divided by the second, ensuring we handle a potential division by zero scenario.

4. Display the result of the operation to the user.

3. Code Program

import java.util.Scanner

fun main() {
    // Initialize a Scanner object to read user input
    val reader = Scanner(System.in)
    
    // Prompt the user to provide the first number
    print("Enter the number from which you want to find the remainder: ")
    
    // Capture and store the first number
    val num1 = reader.nextDouble()
    
    // Prompt the user to provide the second number
    print("Enter the number to divide by (to find the remainder after division): ")
    
    // Capture and store the second number
    val num2 = reader.nextDouble()
    
    // Ensure the second number isn't zero to prevent division by zero
    if (num2 == 0.0) {
        println("Division by zero isn't permissible.")
        return
    }
    
    // Calculate the remainder of the two numbers
    val remainder = num1 % num2
    
    // Display the result to the user
    println("The remainder when $num1 is divided by $num2 is: $remainder")
}

Output:

Enter the number from which you want to find the remainder: 29
Enter the number to divide by (to find the remainder after division): 4
The remainder when 29.0 is divided by 4.0 is: 1.0
