You mean from an binary/executable? Not unless you have debug info compiled in or have access to the source.

Unlike languages like shell, C does not have this kind of metadata available at runtime. The best you can do is scrape the source code with a text processor, or analyze the executable's debugging info.

In the example you provide, it is also most likely that your compiler will optimize away a, b and c, since these variables are not used anywhere in your code.
