Golf Snake

A minimalist implementation of the classic game Snake using minimal code.

---

Rules

To create a Snake program with as few number of characters as possible, adhering to the program constraints.

Program Constraints

• Input Handling: Ability to read W, A, S, D keys for controlling the snake's movement without blocking; case insensitivity; processing of all inputs in the buffer per frame; discarding of invalid inputs (impossible direction changes, characters other than W, A, S, D).

• Movement Handling: Recording of the snake's body position; updating of the snake's body position after movement.

• Food Handling: Properly increasing the snake's length upon eating food; generating new food randomly; ensuring new food does not appear on the snake's body.

• Failure Handling: Detection of failure upon snake collision with walls or itself, leading to program termination.

• Output Handling: Generation of a visual interface on the console; see Sample for the interface layout.

• Frame Length: Frame times should be long enough to make the game human-controllable.

• Library Usage: Allowed to use the standard library and platform-specific libraries (e.g., windows.h for Windows and unistd.h for Linux). Allowed to include -include in compile options instead of preprocessing commands. Not allowed to include your own libraries.

• Stability: Prevention of program crashes under any circumstance.

• Syntax Requirement: Utilization of ISO C99 standard syntax.

• No Undefined Behavior: Ensuring the program exhibits no undefined behavior.

Environment

• Windows 22H2

• clang 17.0.1
