Installing codeblocks

You don't. Code::Blocks has not been actively developed for Mac in years, certainly not for any operating system that runs on Apple Silicon Macs, and I would not recommend installing it for compatibility reasons and current Mac support absence from the developers.

Apple's Xcode from the Mac App Store, though it may install faster via a direct download. Select Xcode 15.0.1 and nothing else for macOS 14.1.1. The Xcode IDE supports C/C++ via clang/clang++, Objective-C/++ and Apple's Swift languages. Xcode is complicated and can support an external smart text editor.

Here are some alternatives to Code::Blocks.

I routinely use Xcode for C and C++ development, and it works quite well once you get over the initial ginormous-tool hurdles. I also use the command line tools and a text editor and a build script or a makefile tool such as meson, depending on what I’m working in.

Other options can include Visual Studio Code, some of the JetBrains IDE tooling, and probably other choices.

If you’re interested in Apple’s preferred Swift, the Playgrounds app is quite capable.

Why do you want to run Code::Blocks? That answer would suggest the best option for you.
