Brainfuck is a very simple programming language with only eight instructions. Despite its simplicity, it’s actually Turing-complete! This language doesn’t use any variables: it works with a large array of bytes as its memory, initialized with all zeros. The interpreter also has a pointer that indicates the current memory location. The pointer can be moved left and right, and all operations on memory are performed on the currently pointed cell.
