BF++ A simple yet powerful Brainfuck interpreter written in C with extended syntax support for readability and usability.
- ✅ Supports standard Brainfuck instructions:
><+-.[] - ➕ Repeat modifiers: Use
>12,<5,+3,-99instead of repeating the same operator - 🔁 Flexible loop brackets: Use any of
[],{}, or()for loops - 📝 Inline comments: Start a comment with
#, anything after is ignored until the end of the line - 📝 Multi-line comments: using
'to start the comment and'to end it - random number generation using
?operator
Make sure you have gcc installed. Then run:

You can also run the interpreter manually:
./bf your_program.bfBrainfuck is an esoteric programming language with only eight instructions and minimal syntax. This project extends Brainfuck with optional improvements for ease of development while staying true to its minimalism.
