Check whether a number is a Palindrome Number

 Palindrome Number

C Program

1.For Loop

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int n,res,old;
    printf("Enter a Number:");
    scanf("%d",&n);
    old=n;
    for(res=0;n>0;n=n/10)
    {

        res = res * 10 + n%10;
    }
    if(res==old)
        printf("IS PALIDROME");
     else
        printf("NOT PALIDROME");
}

2.While Loop

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int n,res;
    printf("Enter a Number:");
    scanf("%d",&n);
    while(n>0)
    {
        res = res * 10 + n%10;
        n=n/10;
    }
     if(res==old)
        printf("IS PALIDROME");
     else
        printf("NOT PALIDROME");
}

3.Do While Loop

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int n,res;
    printf("Enter a Number:");
    scanf("%d",&n);
    do
    {
      res = res * 10 + n%10;
       n=n/10;
    }while(n>0);
     if(res==old)
        printf("IS PALIDROME");
     else
        printf("NOT PALIDROME");
 }
