Palindrome Checker Program 🕵️‍♂️

In Python

Welcome to the Palindrome Checker program! This C application checks whether a given string is a palindrome—a word, phrase, or sequence that reads the same backward as forward. Follow the instructions below to use and understand this program.

Features ✨

• Checks for Palindromes: Determines if the input string reads the same forward and backward, ignoring non-alphanumeric characters and case.
• User-Friendly Loop: Allows multiple checks in one run of the program.
• Input Validation: Handles empty strings and provides informative messages.

How to Use 📜

Compilation ⚙️

1. Ensure you have a C compiler installed (e.g., gcc).
2. Save the code into a file named palindrome_checker.c.

    git clone https://github.com/mdriyadkhan585/palindrome-checker-c
    cd palindrome-checker-c
    gcc -o palindrome_checker palindrome_checker.c

This command compiles the code and generates an executable named palindrome_checker.

Running the Program 🚀

1. Run the compiled executable.

./palindrome_checker

2. The program will prompt you to enter a string.

3. After you enter a string, it will determine if the string is a palindrome and display the result.

4. You will then be asked if you want to check another string. Type y or Y to continue, or n or N to exit.

Example Usage 🖥️

Enter a string: A man a plan a canal Panama
The input string is a palindrome.
Do you want to check another string? (y/n): y
Enter a string: Hello, World!
The input string is not a palindrome.
Do you want to check another string? (y/n): n
Exiting the program.

Code Overview 📝

isPalindrome Function 🔍

• Purpose: Checks if the string is a palindrome.
• How It Works:
  • Uses two pointers to compare characters from the start and end.
  • Skips non-alphanumeric characters and ignores case.

main Function 🏠

• Purpose: Manages user input and interaction.
• Features:
  • Reads the input string.
  • Removes the newline character.
  • Checks if the string is empty and prompts the user accordingly.
  • Asks if the user wants to check another string.

Troubleshooting 🛠️

• Input Issues: If you encounter errors reading input, ensure your environment supports fgets.
• Compilation Errors: Make sure you have a compatible C compiler and that the code is saved correctly.
