C Program To Check Number Is Palindrome Or Not Without Loops

2. #include <stdio.h>
3. int main()
4. {
5.   int number, a = 0, b;
6. 
   
7.   printf("Enter a number to check number is palindrome or not :- ");
8.   scanf("%d", &number);
9. 
   
10.   b = number;
11. restart:
12.   if(b != 0)
13.   {
14.     a = a * 10;
15.     a = a + b%10;
16.     b = b/10;
17. goto restart;
18.   }
19. 
    
20.   if (number == a)
21.   {
22.     printf("%d is a palindrome number.\n", number);
23.   }
24.   else
25.   {
26.     printf("%d is not a palindrome number.\n", number);
27.   }
