dolovnyak / printf

Copies almost all the behavior of the original libc’s printf.

printf

MacOS -

Copies most of the original printf behavior.

Build and run on MacOS

//your main.c file:

#include "ft_printf.h"

int main()
{
  ft_printf("%d LIKE A BOSS %d\n", 1337, 1337);
}

//end of your main.c file


make -C ${PATH_TO_LIB_FOLDER}
gcc ${PATH_TO_LIB_FOLDER}/libftprintf.a -I ${PATH_TO_LIB_FOLDER}/includes main.c
./a.out

Flags:

• #
• SPACE
• 0
• -
• +

Has WIDTH implementation

Has PRICISION implementation

Modifiers:

• hh
• h
• l
• ll
• j
• z
• L

Types:

• char - %c
• string - %s
• pointer - %p
• int - %d, %i
• int in octal system - %o
• unsigned int - %u
• int in hexadecimal system, upper/lower case - %x, %X.
• double - %f, %F
• additional type print int in binary - %b

Remarks:

• On all types except fractional numbers ft_printf wotk or faster or slower within 10 percent.
• Fractional numbers implemented with long arithmetics.
• There are custom tests for a lot of strange and undefind behavior.
• There are generated tests for types diouxXf, that randomize flags, precision, width, modifier and type for both original and ft_printf and compares output.
