C program to check whether given number is palindrome or not

Palindrome Number Checker

Get ready to explore the world of palindromes with our new blog post! We're going to learn about a cool C program that can tell us if a number reads the same forwards and backwards. It's like a word that's the same even if you read it in reverse! We'll show you step by step how the program works, and you'll see how easy it is to use. So, if you're curious about how computers can do these tricks, join us and have some coding fun!

C programming to check whether given number is palindrome or not.

            
#include <stdio.h>

int main() {
    int number, originalNumber, remainder, reversedNumber = 0;

    printf("Enter an integer: ");
    scanf("%d", &number);

    originalNumber = number;

    while (number != 0) {
        remainder = number % 10;
        reversedNumber = reversedNumber * 10 + remainder;
        number /= 10;
    }

    if (originalNumber == reversedNumber) {
        printf("%d is a palindrome.\n", originalNumber);
    } else {
        printf("%d is not a palindrome.\n", originalNumber);
    }

    return 0;
}
            
        

Test the Program

Enter a number:

Explanation

1. Step 1: The program starts by including the standard input/output library stdio.h.
2. Step 2: In the main() function, integer variables number, originalNumber, remainder, and reversedNumber are declared.
3. Step 3: The program prompts the user to enter an integer.
4. Step 4: The original value of number is stored in originalNumber.
5. Step 5: A while loop is used to reverse the digits of number and store them in reversedNumber.
6. Step 6: An if statement checks if originalNumber is equal to reversedNumber to determine if it's a palindrome.
