Wonderful library with lots of useful functions, algorithms and data structures in C, link it with -lC+ Better than C, not as much as c++

Compile the library with

make

To link it with your project use flag -lC+ with GCC

gcc main.c -lC+

Include files depending on functions and modules you will use all header files are available in includes directory

the root of the repo contains

Makefile
make_config.mk
sources 
includes
author
LICENSE
README.md

This makefile does not have rules for every source file, in fact it is static and includes other makefiles. the make_config.mk makefile contains config variables, like what compiler to use, and what modules to compile (we'll get to that later) the sources directory contains multiple subdirectories

base
get_next_line
ttslist
ft_printf

Each subdirectory of sources is called a module Every module contains source files and a make_module.mk file Here's a preview of a make_module.mk file

# MANUALLY GENERATED PART

LOCAL_SRC_DIR = ttslist
MODULE_NAME = ttslist

INCLUDES = ttslist.h

SRC_FILES = ttslist_constructors.c\
	    ttslist_delete.c\
	    ttslist_iterator.c\
	    ttslist_operations.c\
	    ttslist_purge.c\
	    ttslist_tools.c

# AUTO GENERATED PART

include make_config.mk

OBJ_FILES = $(SRC_FILES:.c=.o)
OBJ_FILES := $(addprefix $(OBJ_DIR)/, $(OBJ_FILES))
INCLUDES := $(addprefix $(INC_DIR)/, $(INCLUDES))
...
...
...

We will just pay attention to the MANUALLY GENERATED PART in it you specify a unique module name, and the module directory name, header files to include, and source files the makefile takes care of the rest After adding a new module, we need to load it, so the makefile will compile it and link it to the library. We do that in the make_config.mk

# makefile config specifying locations, compiler and compilation flags

NAME = libC+.a
CC = gcc
FLAGS = -Wall -Werror -Wextra
SRC_DIR = sources
INC_DIR = includes
OBJ_DIR = objects
DELETE_COMMAND = rm
DELETE_COMMAND_FLAGS = -rf
LINKER = ar
LINKER_FLAGS = rc
RANLIB = ranlib
RANLIB_FLAGS =

# IN HERE ADD OR REMOVE MODULES

MODULES = base\
	  ttslist\
	  get_next_line

This make_config.mk also contains other config variables, so you can change the compiler you use or the library name.

Every module should contain a README.md file, containing the documentation and explaining what each function does, with its prototype and usage. finally, the author file contains names or logins of people who contributed to this library.
