Introduction

We’ve done 10PRINT on a lot of machines.

But we haven’t done a comparison between Rust and C.

For no particular reason, I thought it would be fun to compare the two languages side by side.

A race? Yes, please.

10 PRINT Quick review

10 PRINT is a one-liner program that generates a maze-like pattern using the characters / and \.

The program is based on a one-liner BASIC program from the late 70s and 80s. There’s even been a book written about it called: “10 PRINT CHR$(205.5+RND(1)); : GOTO 10”.

I was recently on a video call with a friend, throwing around some ideas for a new product. I mentioned adding large signed numbers in assembly and using two’s complement. He asked me what two’s complement was. I was a little surprised that he didn’t know. He’s been a Java programmer for more than 30 years. Java and Python programmers (and others like gasp Commodore / MicroSoft BASIC) don’t have a native unsigned integer type. The language takes care of the details for you.
