Libft - Printf, Getline and 50+ Utility Functions

Extended Implemented C Library with Printf, Getline and 50+ Utility Functions.

🔧 System Requirements:

• Operating System: Unix-based OS
• Software: make, gcc

Usage

To run the command, open your terminal and follow these steps:

• To create libft.a:

  (cd /path/to/project/directory && make)

• To compile with libft.a:

  (cd /path/to/project/directory && make)
  gcc -o a.out *.o -I </path/to/project/directory>/libft/includes -L /path/to/project/directory -lft

Functions

Ft_printf :

# include "ft_printf.h"

• ft_printf - int ft_printf(const char *format, ...);

• ft_dprintf - int ft_dprintf(int fd, const char *format, ...);

  Types conversions :

  • %c print a single character.
  • %s print a string of characters.
  • %p The void * pointer argument is printed in hexadecimal
  • %d print a decimal (base 10) number.
  • %i print an integer in base 10.
  • %u print an unsigned decimal (base 10) number.
  • %x print a number in lowercase hexadecimal (base 16).
  • %X print a number in uppercase hexadecimal (base 16).
  • %% print a percent sign.

  Flag directives (use them between '%' character and the type conversion):

  • - left align the result within the given field width.
  • + use a sign (+ or -) to prefix the output value if it's of a signed type.
  • # When it's used with the o, x, or X format, the # flag uses 0, 0x, or 0X, respectively.
  • 0 If width is prefixed by 0, leading zeros are added until the minimum width is reached.
  • blank (' ') use a blank to prefix the output value if it's signed and positive.
  • . the precision specification
  • \<number\> the width specification field.

Ft_getline :

# include "ft_getline.h"

• ft_getline - char *ft_getline(int fd);

Others Functions :

# include "ft_libft.h"
