From Prof. Sarah Nadi's challenge...

This small toy will prompt a warning if a method has more than 3 arguments.

How to compile:

Install libclang: on macOS, make sure your Homebrew is successfully installed, then type "brew install llvm"

If you are using other platforms or installing libclang to another path, please modify the CMakeLists.txt in libclang-analyze and set the libclang_include_path and libclang_lib_path to the corresponding locations.

Go to libclang-analyze.

Then type cmake . and make to generate the executable file.

Usage: clang_analyze_arguments <file>
