Palindrome Program in C – Check Number (Iterative, Function, Recursive)

A palindrome program in C checks whether a number reads the same forwards and backwards. Numbers like 121, 1331, and 12321 are palindromes; 12345 is not. The standard technique is to reverse the digits and compare with the original. This page covers three versions: a simple iterative solution, a clean function-based version, and a recursive …

C program to check whether a given string is palindrome or not

A palindrome is a word, sentence, or sequence that reads the same forward and backward — ignoring differences in capitalization for word-level palindromes. Examples: “racecar”, “GADAG”, “level”, “9009”. The most efficient check uses a two-pointer approach: one pointer starts at the left end, one at the right, and they advance toward each other until they …
