Language used

• C

Requirements of the project:

• Student are given the prototype for functions and must re-create behaviors as the originals
• Heap allocated memory space must be properly freed when necessary (e.g use for Malloc)
• A Makefile must be used to create a static library called libft.a
• To use functions in library the header libft.h is used
• To get a full project outline please refer to the pdf

Installation

1. Create a new folder (e.g test_libft)
2. git clone repo inside test_libft
3. Enter /libft folder
4. To compile Makefile type:

make re

5. Go back to /test_libft

How to use libft library

1. Inside /test_libft create a .c file (e.g.test.c)
2. Open test.c and add library header#include 'libft/libft.h'
3. Create a int main()
4. Call a function from libft.h (e.g. ft_putstr("Hello World")) <- ft_putstr() is a LIBFT function to display a string to standard output
5. To compile file type:

gcc test.c libft/libft.a

6. To execute file type:

./a.out

7. You should see

Hello World

displayed to standard output

Makefile commands

• make re - recompile library when changes are made to functions
• make clean - removes all function objects
• make fclean - removes all function objects created with library object
