Cat Command Clone in C

This is a simple C program that mimics the basic functionality of the Unix/Linux cat command. It reads a file and prints its contents to the standard output.

📁 File Structure

• cat.c – Main C source file containing the code to read and print a file.

🔧 Compilation

To compile the program, use gcc:

gcc cat.c -o cat

▶️ Usage

Run the compiled program with a filename as an argument:

./cat <filename>

Example

./cat sample.txt

⚠️ Error Handling

• If no filename is provided, the program prints a usage message.
• If the specified file doesn't exist or can't be opened, an error message is shown.

✅ Features

• Read file content character by character.
• Simple and beginner-friendly code.
• Works with any readable text file.

❌ Limitations

• Does not support multiple files.
• No support for flags (e.g., -n, -E) like the original cat command.
