hey !!
we have a Makefile file in repo for to keep all files in a singe file (40+ .c file in 1 .a file)
and
.h file is a library file, it has a lot of function define
we can compile main.c file, main.c has #include "libft.h"
and
compile! with;
cc main.c libft.a
cc (compiler)
main.c(main file)
libft.a (all lib files needed in archived with Makefile);
