Question

Write a C program to check if it is a palindrome number or not using a recursive method

Answer 1

#include <stdio.h> #include <conio.h> int reverse(int num); int isPalindrome(int num); int main() { int num; printf("Enter a number: "); scanf("%d", &num); if(isPalindrome(num) == 1) { printf("the given number is a palindrome"); } else { printf("the given number is not a palindrome number"); } return 0; } int isPalindrome(int num) { if(num == reverse(num)) { return 1; } return 0; } int reverse(int num) { int rem; static int sum=0; if(num!=0){ rem=num%10; sum=sum*10+rem; reverse(num/10); } else return sum; return sum; }
