This Brainfuck environment has just 16 bytes memory.
Tutorial
Brainfuck is an esoteric programming language. You can write programs with only 8 commands: >, <, +, -, ., ,, [, ].
Commands
| Command | Meaning |
|---|---|
> | Increment the data pointer (to point to the next cell to the right). |
< | Decrement the data pointer (to point to the next cell to the left). |
+ | Increment (increse by one) the byte at the data pointer. |
- | Decrement (decrease by one) the byte at the data pointer. |
. | Output the byte at the data pointer. |
, | Accept one byte of input, storing its value in the byte at the data pointer. |
[ | If the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command. |
] | If the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command. |
