Nice isn’t it?\ \ Well, but you’re asking what this is all? I will give you the related links as soon as my link-system is working. For now this little explanation should help you, otherwise google for “Brainfuck tutorial”.\ \ Brainfuck is a very small (esoteric) programming language. It was design by a Swiss guy with the aim to write the smallest possible compiler for a Turing-complete language (his size is about 240 bytes).\ \ And sure Brainfuck is Turing-complete.\ \ The context of the language is a large array with (depending on the compiler and/or interpreter) about 30’000 array cells (each cell will be initalized with 0).\ \ The 8 instructions:\ > change the pointer to the next cell\ < change the pointer to the last cell\ + increment the cell value\ - decrement the cell value\ [ begin of loop\ ] end of loop (a loop stops is the value of the actual cell is 0)\ , read a value (input) into the actual cell\ . Print out the ascii sign belonging to the cell value\ \ Depending on that I will print you my bf-code of above again, this time with comments and so on:
