#To use this Makefile, create a directory structure as follows:
#
#```
#project_folder/
#  |--- src/
#  |     |- file1.c
#  |     |- file2.c
#  |     |- file3.c
#  |     ...
#  |
#  |--- obj/
#  |
#  |--- Makefile
#```
#
#Place your C source files inside the `src/` directory. Then, execute `make` command in the `project_folder/` directory to compile and link all the source files into a binary named `my_binary`. The compiled binary will be created in `project_folder/`.
#
#To clean the generated object files and binary, execute `make clean`.
