Brainfuck
The brainfuck programming language is an esoteric (weird and unusual) programming language. It was created by Urban Müller in 1993.[1][2] It has eight instructions (commands) which operate (do things on) a tape.[1] Instructions are done one by one, in order.[1] The tape has multiple sections.[1] Each section is a number.[1][2] Each section is, in the beginning, zero.[1] Brainfuck is like a Turing machine.

Instruction table[change | change source]
| Instruction | Action |
|---|---|
| + | Add one to the current tape section. |
| - | Subtract one from the current tape section. |
| < | Move to the tape section to the left of the current one. |
| > | Move to the tape section to the right of the current one. |
| . | Print the value of the current tape section as an ASCII symbol. |
| , | Read an ASCII symbol into the current tape section as a number. |
| [ | If the current tape section is zero, go to the matching ], skipping the instructions in between. |
| ] | If the current tape section is not zero, go back to the matching [, and do the code after it again. |
Examples[change | change source]
[-]
If the current section is not zero, these three commands subtract one until the current section is zero. Otherwise, they leave it at zero.
+++--
These five commands first add three to the current section. Then, they subtract two from the current section. Since , these five commands are the same as "+" alone.
Derivatives[change | change source]
As a result of brainfuck's fame, many derivatives (versions) of brainfuck have been created. These include Brain-Flak,[3] pbrain,[4] and tinyBF.[5] Most are also Turing complete, just like brainfuck.
