I am new to C++ and need to get a compiler compatible with a Mac OS Catalina (version 10.15.5). The Xcode 12.2 beta is too large a file for my computer (or so says the error message). Is there a stripped down version i can use? The book I'm using, Introduction to C by Alex Allain on the Cprogramming site says there is a developer's version that takes up less memory. But I can't find it on the download site. Help!
