I'm working on a Brainfuck challenge where you take 8 characters as input, either '0' or '1'. The output should be the corresponding decimal number. The process starts with taking the ASCII values of these characters—'1' is 49 and '0' is 48. After that, I need to subtract 48 from the first 8 cells to convert the ASCII values into binary (1s and 0s). Finally, the code uses three additional cells to represent the hundreds, tens, and units for the final output. My code seems to work fine until I reach adding cell 6 (which represents 8). At this point, the units cell can only display values from 0 to 7 since we are dealing with single cell values. However, adding 6 to what's already in there causes an overflow (13), which I need to somehow split into 1 for the tens and 3 for the units. How should I approach this overflow issue? Am I on the right track, or should I convert the binary to a whole number first (maximum 255 is manageable) and then break it down into digits? Any guidance would be greatly appreciated!

To avoid overflow, convert the binary input into a whole number first and then break it down into individual digits. You can do this by dividing the whole number by 10 to determine the digits. Here's a helpful explanation on how to implement it: [Link to Stack Overflow]. Also, consider creating a loop that processes each bit of input one at a time to keep your code clean and avoid duplication.
Glad to hear you're working on it! Loops can really simplify the problem when processing bits.
Honestly, Brainfuck isn’t designed for serious tasks. If you’re looking to learn programming, traditional languages are a better fit. But if you’re just having fun, go ahead with it! Just keep in mind it’s a pretty niche language, and resources might be limited.
I totally get that—I'm using Brainfuck just for fun when I have some free time. I'm also exploring more serious programming languages alongside!
Exactly! Brainfuck is a fun challenge, but always good to balance with practical learning!
Thanks for the suggestion! I've actually updated my code a bit since posting, using a "catch cell" approach to manage the digits better. I appreciate the links!
