C Program to Check if the string is palindrome or not

This tutorial explains c program to check if the string is palindrome or not with C source code, sample output, and step-by-step execution flow.

#include <stdio.h>
#include <string.h>
int main() {
    char str[] = "level";
    int i, len = strlen(str), flag = 1;
    for (i = 0; i < len / 2; i++) if (str[i] != str[len - i - 1]) flag = 0;
    if (flag) printf("Palindrome string
");
    else printf("Not a palindrome string
");
    return 0;
}

Palindrome string

Practice This Program

In this program, the input is read first when required, the core logic is applied step by step, and the final result is displayed using printf(). Follow the execution flow beside the code to understand how each statement contributes to the output.
