    int n, rev = 0, rem;

    printf("Enter number: ");
    scanf("%d", &n);

    while(n != 0) {
        rem = n % 10;
        rev = rev * 10 + rem;
        n /= 10;
    }

    printf("Reverse = %d", rev);
    return 0;
}

---

8. Check Palindrome

#include <stdio.h>

    int n, temp, rev = 0, rem;

    printf("Enter number: ");
    scanf("%d", &n);

    temp = n;

    while(n != 0) {
        rem = n % 10;
        rev = rev * 10 + rem;
        n /= 10;
    }

    if(temp == rev)
        printf("Palindrome");
    else
        printf("Not Palindrome");

    return 0;
}

---
