Lisp Macros: A practical approach

On my way to learn Lisp I have discovered the all powerful and feared so called Macros, then after spending a hard time trying to understand them and their usefulness I said to myself, I FINALLY GOT IT.
I couldn’t be more wrong, I was thinking that the only purpose of Macros was to define new control structures and that was all I needed to know until I start reading more and more on the subject and a whole new world has comes to me !

Why does the C library use macros and functions with same name?

I am reading ‘The Standard C Library’ by PJ Plauger which is really interesting. The book explains not only how to USE the library but also how it is implemented.

Is there a way to compare and record changes to code without VCS?

I’m working for a client that has no version control system in place. I want to record changes to code without having to add all changes to a spreadsheet. I’m restricted to using Notepad++ so would a plugin or macro for this be another option?

Byte code weaving vs Lisp macros

I have been reading about the libraries people have written for languages like Java and C# that make use of byte code weaving to do things like intercept function calls, insert logging code, etc. I have also been reading up on Lisp/Clojure macros in an attempt to better understand how to utilize them. The more I read about macros, the more it seems like they provide the same kind of functionality as byte code weaving libraries. By functionality, I mean the ability to manipulate code at compile time.

Why can’t we declare ‘extern C’ for C++ macro’s?

I am new to C/C++. Wanted to know why we cannot declare ‘extern C’ for C++ macro’s similar to methods/functions…which will allow macro’s defined in C++ file to be accessed in .c files.

When would I require a Macro instead of a function?

I am new to Clojure, I am new to Macros and I have no prior background in Lisp.
I went on to create my own switch case like form and ended up with this:
