Check whether a number is palindrome Dry Run in C

Check whether a number is palindrome is an interactive C dry run visualizer from the For programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.

Check whether a number is palindrome Program Code

#include <stdio.h>
int main() {
    int num, reversed = 0, temp;
    printf("Enter a number: ");
    scanf("%d", &num);
    
    int original = num;  // Save original value
    
    for(temp = num; temp != 0; temp /= 10) {
        reversed = reversed * 10 + (temp % 10);
    }
    
    if(original == reversed) {
        printf("%d is a palindrome\n", original);
    } else {
        printf("%d is NOT a palindrome\n", original);
    }
    return 0;
