Finding The Last Digit Of A Number

Finding the last digit of a given number N. We will discuss the approach, present a step-by-step solution, and provide a code example to solve this problem effectively.

Understanding the Problem

The problem is to determine the last digit of a given number N. To solve this, we need to extract the last digit from N and identify it. The last digit is the rightmost digit in a number, and it plays a significant role in various mathematical and computational operations.

Approach

To find the last digit of a number N, we can follow a simple approach. We will use the modulo operator (%) in Java to calculate the remainder when N is divided by 10. The remainder will be the last digit of the number.

Step-by-Step Solution:

Let's break down the problem into steps:

Step 1: Accept the input value for N.

Step 2: Calculate the remainder by dividing N by 10 using the modulo operator (%).

Step 3: Print the last digit.

Element 1: Accepting User Input

First, we need to accept the input value for N. Let's write a simple program to accomplish this:

Element 2: Calculating the Last Digit

Once we have the input number N, we can calculate the last digit using the modulo operator. 

Here's how we do it:

Element 3: Printing the Result

Finally, we can print the last digit to reveal the outcome. Let's complete the program:
