Reversing an Integer: A Step-by-Step Guide

When working with integers in C++, understanding how to reverse a number is a fundamental skill. This process may seem daunting, but with the right tools and knowledge, it’s easier than you think.

The Magic of Loops

To reverse an integer, we’ll utilize the mighty while loop. This loop allows us to iterate through a sequence of numbers until a specific condition is met. In this case, our condition is n!= 0, where n is the input integer.

The Reversal Process

Here’s how it works:

• The user inputs an integer, which is stored in the variable n.
• The while loop kicks in, and with each iteration, we calculate the remainder of n divided by 10. This gives us the last digit of the number.
• We then add this digit to our reversed_number variable, effectively building the reversed integer.
• To prepare for the next iteration, we decrease the value of n by a factor of 10.

The Final Result

Once the loop has finished iterating, we’re left with the fully reversed integer stored in reversed_number. This value is then printed to the screen for the user to see.
