Palindrome number in C
A palindrome number is one that remains the same on reversal. Some examples are 8, 121, 212, 12321, -454. To check if a number is a palindrome or not, we reverse it and compare it with the original number, if both are the same, it’s a palindrome otherwise not.
C program for palindrome number
#include <stdio.h>
int main()
{
int n, r = 0, t;
printf(“Enter a number to check if it’s a palindrome or not\n“);
scanf(“%d”, &n);
t = n;
while (t != 0)
{
r = r * 10;
r = r + t%10;
t = t/10;
}
if (n == r)
printf(“%d is a palindrome number.\n“, n);
else
printf(“%d isn’t a palindrome number.\n“, n);
return 0;
}
Output of the program:
Function to check palindrome number
int check_palindrome(int n) {
int t, r = 0;
t = n;
while (t != 0) {
r = r * 10;
r = r + t%10;
t = t/10;
}
if (n == r)
return 1;
else
return 0;
}
