Forest fire simulation based on the Drossel-Schwabl forest fire model

The program simulates a forest fire in a terminal window. It is based on the model created in 1992 by Barbara Drossel and Frank Schwabl. Written in C for Linux.

The program consists of three files:

File	Description
main.c	setup and main loop
grid.h	constants, cell states, declarations
grid.c	cell colors and definitions

Optionally, set the grid dimensions and other constants in grid.h before building.

Constant	Description
ROWS	number of rows
COLS	number of columns
STEPS	number of simulation steps
TIME	delay between steps in milliseconds
TREE_CHANCE	chance of a tree growing in each step
FIRE_CHANCE	chance of a fire starting in each step

Then build the program and watch the world burn.

Build with gcc

gcc main.c grid.c -o forest-fire
./forest-fire

Build with CMake

cmake -B build
cmake --build build
./build/forest-fire
