🧩 2048 Game in C (Console Version)

This project is a console-based implementation of the 2048 game, developed entirely in C as part of a university assignment in a systems programming course.

The game supports variable board sizes, score tracking, and dynamic memory handling using pointer arithmetic without any 2D arrays.

---

🎯 Objectives

• Simulate the original 2048 game using only C.
• Implement logic using a flat 1D array and pointer arithmetic.
• Allow playing multiple rounds with different board sizes and winning values.
• Handle user input and game state management via clean modular code.

---

📚 Features

• 🟦 Dynamic board sizes: supports 2×2, 3×3, and 4×4 (as seen in main.c)
• 🧠 Win condition can be adjusted (e.g., 16, 32, 2048)
• 🔁 Multiple games can run one after the other
• 🎲 Random tile generation (value 2 with 70% chance, 4 with 30%)
• 🎯 Game ends when:
  • No valid moves are left
  • A tile reaches the target value (e.g., 2048)
• 🎮 Console-based interface:
  • n/N = New game
  • r/R, l/L, u/U, d/D = Movement
  • e/E = Exit

---

🗂️ File Structure

• main.c – Runs 3 games with different board sizes and goals
• game.c / game.h – Game logic, input handling, move validation
• board.c / board.h – Board rendering, initialization, random tile generation
• Makefile – For compiling and cleaning the project

---

🛠️ Compilation & Execution

This project is built to run in a Linux environment (e.g., Ubuntu) and includes a Makefile for simple build and cleanup.

🔧 Build & Run

To compile and execute the game:

make        # Compile all source files
./a.out     # Run the compiled game
make clean  # Delete all object files and the executable

📷 Example Output

Score 0 Best 0
--------------------------
|      |   2  |      |
|      |      |      |
|   4  |      |      |
--------------------------
Please choose one of the following options:
N/n - New Game
R/r - Move Right
L/l - Move Left
U/u - Move Up
D/d - Move Down
E/e - Exit

🧠 What I Learned

• Working with pointer arithmetic to simulate 2D grids in a 1D array
• Writing modular code using .c and .h file separation
• Handling random tile generation with controlled probability
• Managing user input and real-time game state
• Creating a flexible and dynamic C program that complies with strict standards
