GoKawiilThis small structure is the seed of every serious C project. Once you can organize your files this way, you’re ready to grow into larger systems, libraries, tools, and applications that others can use and build upon.
Run make clean to delete the binary and rebuild fresh.
Add another pair of files, src/farewell.c and include/farewell.h , with a goodbye function, and call it from main.c .
Create the directories and files shown above.
Even small C utilities benefit from structure, you’ll thank yourself later when you revisit your code.
Output binary The compiled executable (here my_program ) stays in the project’s root for convenience.
Makefile Defines how to build the program. You can run make instead of typing long gcc commands.
main.c The entry point of your program, this file usually just calls functions from src/ .
src/ Contains source files ( .c ) that implement functions declared in headers.
include/ Holds header files ( .h ), declarations of functions, constants, and types. You include these in .c files using quotes:
