This project creates a library with standard libc functions and several other generic functions, which will be used for other 42 projects.
The purpose is to help us develop a deep understanding of the standard libc functions and how to use them.
- Allowed functions:
malloc
,free
,write
- All heap allocated memory space must be properly freed when necessary

To test the library, create a
test.c
file to compile with thelibft.a
library
# include "libft.h"
# include <stdio.h>
int main(void)
{
char *str;
int ret;
str = "123456789";
ret = ft_atoi(str);
printf("ret is %d\n", ret);
return (0);
}
Run the commands below. You can replace the
test.c
with your own test file
$ git clone https://github.com/DelicaTessa/42-libft.git
$ cd 42-libft
$ make
$ make bonus
$ gcc test.c libft.a
$ ./a.out
