Write a program to check a number is palindrom or not

//Write a program to check a number is palindrom or not
#include<stdio.h>
#include<conio.h>
void main()
{ int n,a,r=0,temp;
clrscr();
printf("Enter any number:\n");
scanf("%d"&n);
temp = n;// copy number to temp
while(n)//run loop until n have some value
{
 a=n%10;//from this we get last digit
 r=r*10+a;
 n=n/10;
}
if(temp==r)
printf("%d is Palindrom",temp);
else
printf("%d is not Palindrom",temp);
getch();
}
/*For example we input a number 121 then
a = 121%10 = 1
r = 0*10 + 1 = 1
n = 121/10 = 12

a = 12%10 = 2
r = 1*10 + 2 = 12
n = 12/10 = 1

a = 1%10 = 1
r = 12*10 + 1 = 121
n = 1/10 = 0

temp is equal to r, so that 121 is Palindrom*/
