Yes, use the -E option. Note that this sends the results to standard output, typically your screen.

See gcc.gnu.org/onlinedocs/gcc/Option-Summary.html for a summary of options.

By the way, #include statements are typically used to include header files. Header files should have only function prototypes, not function definitions. A web search will bring up several sources of explanation of the differences between the two.
