Steps to Check Palindrome in C:

  1. Input a number.
  2. Run while loop with condition (number != 0)
  3. Divide the number by 10
  4. Store the remainder into another variable reverse as stated reverse = reverse *10 + remainder
  5. Update the number as number = number/10
  6. After the loop ends, check if reverse == original_number
  7. If yes, then the number is palindrome else not.

Here is the implementation of the steps in C.
