This is a simple interpreter for the brainfuck programming language, written in C.

• All characters except the eight commands ><+-.,[] are ignored and treated as comments.

• The array has 30,000 cells and each cell in the array contains a byte (most commonly 8 bits).

• Moving the pointer outside the bounds of the array will result in undefined behavior.

Edit config.mk to match your local setup (brain is installed into the /usr/local namespace by default).

Afterwards enter the following command to build and install brain (if necessary as root):

make clean install

After successfully installing brain, you can run it:

brain <file>

This is an example of running brain:
