At Hive, students are not allowed to use library functions. We can only submit wholly self-written functions (no strlen, strdup, bzero etc.).
ft_printf must be formatted in the same manor as libc's printf. For example:
ft_printf("%s is %d years old\n", "Lucas", 42);
printf("%s is %d years old\n", "Lucas", 42);Should give back:
Lucas is 42 years old
Lucas is 42 years oldThe project is complicated as the number of parameters is indefinite. I use variadic arguments in this case.
ft_printf must achieve the following mandatory requirements:
- Manage the following conversions:
s,S,p,d,D,i,o,O,u,U,x,X,c&C - Manage
%% - Manage the flags
#,0,-,+&space - Manage the minimum field-width
- Manage the precision
- Manage the flags
hh,h,l,ll,j, &z.
The function must conform to Hive's norm.
The function cannot leak. All errors must be handled carefully. In no way can the function quit in an unexpected manner (Segmentation fault, bus error, double free, etc).
Allowed functions are write, getloacale, malloc, free, exit and the three functions of stdarg. Everything else is forbidden.
To compile, run make. This will compile libftprintf.a. To use, include ft_printf.h (located inside includes directory) and use just like printf:
#include "ft_printf.h"
int main(void)
{
ft_printf("%s, %s!\n", "Hello", "world");
return (0);
}Then compile with a program:
gcc -Wall -Werror -Wextra main.c libftprintf.a -I includes
