Goal

You must recode the printf function from the C library according to the C99 standard. Your function should be prototyped like the printf function.
You do not have to implement the C library printf buffer handling.
You must process all printf formating flags except the following (which are optional):

• float or double types management,
• %n flag management,
• " * " , " ’ " and " I " (capital i) flags management.

You must add a %b formating flag, which prints unsigned numbers in a binary base.
You must also add a %S formating flag, which prints a character string (like %s). However, non-printable characters (ASCII value strictly smaller than 32 or greater or equal than 127) must be represented by a back- slash to be followed by the character’s value in octal base.

Unit tests

#include <criterion/criterion.h>
#include <criterion/redirect.h>
#include "my.h"

void redirect_all_std(void)
{
  cr_redirect_stdout();
  cr_redirect_stderr();
}

Test (my_printf, simple_string, .init=redirect_all_std)
{
  my_printf("hello world");
  cr_assert_stdout_eq_str("hello world");
}

Examples

char str[5];

my_strcpy(str, "toto");
str[1] = 6;
my_printf("%S\n", str);
