Functions: Palindrome Check

Write a C function is_palindrome that takes an integer as input and returns 1 if the number is a palindrome (reads the same forwards and backwards), and 0 otherwise.

Hint:

Solution

#include 

// Function to check if a number is a palindrome
int is_palindrome(int num) {
    int reversed = 0, original = num;
    while (num != 0) {
        reversed = reversed * 10 + num % 10;
        num /= 10;
    }
    return (original == reversed);
}

int main() {
    int num;
    printf("Enter a number to check if it is a palindrome: ");
    scanf("%d", &num);

    if (is_palindrome(num))
        printf("%d is a palindrome.\n", num);
    else
        printf("%d is not a palindrome.\n", num);

    return 0;
}

Explanation

The is_palindrome function checks if a given number is a palindrome by reversing its digits and comparing the reversed number with the original number. If they are the same, the number is a palindrome. The main function takes a number as input, calls the is_palindrome function, and prints the result.
