Inside thewhile loop, the given number is divided by 10 using% (modulus) operatorand then storing theremainderin thereversenumvariable after multiplying thereversenumby 10.When we divide the number by 10, it returns the last digit as remainder.This remainder becomes the first digit ofreversenum,...
In this section, we are going to see how to reverse a number using various methods like while loop, recursion, for loop and do while loop with the help of examples. Example 1: Find Reverse Number in C++ Using While Loop Before moving to the program, let’s first understand how while l...
Then the while loop is used until n != 0 is false (0). In each iteration of the loop, the remainder when n is divided by 10 is calculated and the value of n is reduced by 10 times. Inside the loop, the reversed number is computed using: reverse = reverse * 10 + remainder; ...

3. Using the ‘/‘ and ‘%‘ Operators The first idea to solve this problem is to use arithmetic operations. First, we initialize the reversed result variable as 0. Then, we use a loop to repeatedly divide the input number by 10, adding the remainder to the current result x 10 in ea...
