🐍 Snake Game in C++

A classic console-based Snake Game written in C++, designed for beginners to learn:

• Game loops
• Real-time input handling
• Tail-follow mechanics
• Collision detection
• Rendering tricks
• Practical use of arrays
• Smooth screen updates

This version includes:

✔ Smooth screen rendering (no flicker)
✔ Wall Mode & No-Wall (Wrap-Around) Mode
✔ Snake tail that grows properly
✔ Speed boost
✔ Score system
✔ Collision detection
✔ Cursor hiding for clean visuals
✔ Beginner-friendly structure

🚀 Features

🎮 Gameplay

• Move using W / A / S / D
• Eat fruit (F) to grow
• Gain +1 score per fruit
• Press Spacebar for temporary speed boost
• Press X to exit instantly

🧱 Game Modes

1. Wall Mode → hitting the wall ends the game
2. No-Wall Mode (Wrap-Around) → snake appears from the opposite side

---

⭐ Mechanics Explanation (Beginner Friendly)

▶ Snake Movement

Each frame runs the loop:

input() → logic() → gameOverFunc() → draw()

▶ Tail Logic

• The snake head moves first
• Each tail segment copies the position of the segment in front of it
• The first tail segment follows the old head position

Arrays used:

int tailX[100], tailY[100];
int nTail;

Smooth Rendering

Instead of clearing the screen, we reposition the cursor:

SetConsoleCursorPosition()

This removes flicker completely.
