C Program to Check whether a Number is Palindrome or Not

A palindromic number or numeral palindrome is a number that remains the same when its digits are reversed. Like 16461, for example, it is "symmetrical". The termpalindromic is derived from palindrome, which refers to a word (such as rotor or "racecar" or even "Malayalam") whose spelling is unchanged when its letters are reversed. The first 30 palindromic numbers (in decimal) are:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, … (sequence A002113 in OEIS).

#include<stdio.h>

#include<conio.h>

void main()

{

    int num,rev=0,rem,temp;

    printf("Enter a number:");

    scanf("%d",&num);

    temp=num;

    while(num>0)

    {

        rem=num%10;

        rev=rev*10+rem;

        num=num/10;

    }

    if(rev==temp)

        printf("%d is palindrome number",temp);

    else

        printf("%d is not palindrome number",temp);

    getch();

}
