Palindrome number in C by R4R Team

Palindrome number:
A number which is same when we read that number in both forward and reverse direction.

Example-
Palindrome number:
12321
123321
454

Not palindrome number:
678
456
123421


program-

#include < stdio.h>
int main()
{
int n,a=0,n1;
printf("Enter number\n");
scanf("%d",&n);
n1=n;
//reverse the number
while(n)
{
a=a*10+n%10;
n=n/10;
}
//now compare number and it's reverse
if(n1==a)
printf("Palindrome");
else
printf("Not palindrome");
return 0;
}

output-

Enter number
12221
Palindrome

Enter number
12331
Not palindrome

-In this program, we take a input of the integer number.
-then we reverse the number and store in variable 'a'.
- then compare both actual number and reverse number, if both are same then input number is considered as a palindrome number otherwise not.
