📜 Repository Overview

Welcome to my collection of C programming projects. This repository contains four distinct applications designed to explore fundamental programming concepts, algorithm design, and user interaction.

Projects included in this repository:

1. Tic-Tac-Toe (XO Game): An interactive Player vs. Computer strategy game.
2. Number Guessing Game: A loop-based logic game with "High/Low" feedback.
3. Temperature Converter: A precision tool for Celsius/Fahrenheit conversion.
4. Arithmetic Calculator: A switch-case based mathematical utility.

🌟 Featured Project: Command-Line Tic-Tac-Toe (XO)

This is the flagship project of the repository—a fully functional, console-based implementation of the classic board game.

🎮 How It Works

• Opponent: You play as 'X' against the Computer's 'O'.
• The Engine: The game utilizes a robust checking algorithm to detect wins (rows, columns, diagonals) or ties after every move.
• Smart Play: The computer automatically reacts to your moves using randomized logic for replayability.
• Loop: Includes a replay feature so you can play multiple rounds without restarting the program.

// Sample Logic Snippet
if (winner == PLAYER) {
    printf("You Win!");
} else if (winner == COMPUTER) {
    printf("You Lose!");
}

📂 Utility Projects

2. 🎲 Number Guessing Game

A logic-building exercise focusing on loops and conditionals.

• Core Concept: Uses srand(time(0)) to generate a truly random number between 1 and 100 every session.
• Mechanics: The program guides the user with "Too High" or "Too Low" hints until the correct number is found.
• Score: Tracks the total number of guesses taken.

3. 🌡️ Temperature Converter

A scientific utility for unit conversion.

• Core Concept: Mathematical formula implementation and character handling.
• Features:
• Converts Celsius to Fahrenheit ().
• Converts Fahrenheit to Celsius ().
• Includes case-insensitive input (accepts 'c' or 'C').

4. 🧮 Simple Calculator

A fundamental tool demonstrating control flow.

• Core Concept: Utilizes the switch statement for efficient operation selection.
• Operations: Supports Addition (+), Subtraction (-), Multiplication (*), and Division (/).
• Precision: Uses double data types to handle decimal calculations accurately.

🛠️ Build & Run Instructions

To run these projects, you need a C compiler (like GCC). I recommend saving each code block into its own file (e.g., game.c, calc.c).

1. Clone the Repository:

git clone https://github.com/YourUsername/C-Arsenal.git

2. Compile (Example for Tic-Tac-Toe):

gcc tictactoe.c -o game

3. Run:

./game   # On Linux/Mac
game.exe # On Windows

🧩 Concepts Mastered

• Arrays: 2D arrays used for the Tic-Tac-Toe grid.
• Pointers & Memory: Efficient data handling.
• Control Flow: Complex if-else, switch, and do-while loops.
• Standard Libraries: <stdio.h>, <stdlib.h>, <time.h>, <ctype.h>.
