I use IntelliJ Idea CE for Java and I like its features like it tells which of the declared parameters has never been used, simplification of code, auto-including libraries for methods selected from suggestions, etc.
Is there a free IDE for C language which can give me such kind of features. I need to mostly work with pointers. It will be good if the IDE tells me things like the pointer is never freed, etc.
I currently use Visual Studio Code on Windows 10. It doesn't suggest me functions from the libraries I haven't included.
