TinyF

Not to be confused with TinyBF.

TinyF is a brainfuck derivative created by Cursor AI and prompted by User:None1.

Specification

TinyF has the following commands:

• > - Move the memory pointer to the right.
• < - Move the memory pointer to the left.
• + - Increment the memory cell at the pointer.
• - - Decrement the memory cell at the pointer.
• . - Output the character signified by the cell at the pointer.
• , - Input a character and store it in the cell at the pointer.
• * - Multiply the current cell value by the next cell value.
• ! - If the current cell value is zero, skip the next command.

Interpreter

Written in C++, generated by the Cursor AI.

#include <iostream>
#include <vector>

class TinyFInterpreter {
private:
    std::vector<int> tape;
    int ptr;
