function I have to make

• ft_strlen (man 3 strlen)
• ft_strcpy (man 3 strcpy)
• ft_strcmp (man 3 strcmp)
• ft_write (man 2 write)
• ft_read (man 2 read)
• ft_strdup (man 3 strdup, you can call to malloc)

work process

1. write code in C to remember libft
2. convert them to .s file with

gcc -s -C <filename.c>

gcc <filename.c> -s

in mac

gcc -S -o ft_strlen.s ft_strlen.c

How to use gdb
