This file contains a brief description of The custom printf c files in this directory.

• _putchar.c : Countains a function _putchar which writes character to the stdout that it gets from buffer.
• address_sp.c : Contains a function format_p for printf specifier that prints an address denoted by - %p. The function prints the address of a given argument in hexa form.
• binary_sp.c : Contains a function format_b for custom printf specifier that prints the binary form of a given number.
• custom_fun.c : Contains three custom printf functions:
  • format_r : A function that prints the reversed version of a given string.
  • format_R: A function that converts a string to ROT13(replaces a letter with the 13th letter after it in the alphabet) and prints out the result.

• flag_0.c : contains four printf functions that perform 0 flag (The value will be zero padded):
  • flag_0 : function that prints d, i, and u while passing to another function if the specifier is o, x, or X
  • flag_0o : function that prints octal with 0 flag.
  • flag_0x : function that prints hexa(small) with 0 flag
  • flag_0X : function that prints hexa(capital) with 0 flag
• flag_hash.c : contains four printf functions that perform # flag (prefix 0 if octa and 0x or 0X for hexa):
  • flag_hash : function that checks for octal or hexa and pass them to their respective function
  • hash_o : function that prints octal with # flag.
  • hash_x : function that prints hexa(small) with # flag
  • hash_X : function that prints hexa(capital) with # flag
• flag_left.c : contains four printf functions that perform - flag (value is to be left adjusted):
  • flag_left : function that checks for d, i, u, o, x, or X and pass them to their respective function
  • flag_left_diu : function that prints d, i, and u with - flag.
  • flag_left_o : function that prints octa with - flag
  • flag_left_xX : function that prints hexa with - flag
• flag_plus.c : Contains a function flag_plus which perform the + flag (print + before integer if positive and - if negative.)
• flag_right.c : contains four printf functions that perform field width (value is to be right adjusted):
  • flag_right : function that checks for d, i, u, o, x, X, c, or s and pass them to their respective function
  • flag_right_diuc : function that prints d, i, u and c with field width.
  • flag_right_o : function that prints octa with field width
  • flag_right_xX : function that prints hexa with field width
  • flag_right_s : function that prints string with field width
• flag_spc.c : Contains a function flag_spc which performs the space flag (print a space before a positive value)
• helper_func.c : Contains four functions used throughout the program as a helping function
  • itos : Function that converts integer to string
  • utos : Function to convert unsigned int to string
  • num_len : Function that counts the length of a number
  • _strlen : Function to count the number of string
• hexa_sp.c : Contains two functions which perform hexa specifier denoted by %x or %X
  • format_x : Function that prints hexadecimal using small characters
  • format_X : Function that prints hexadecimal using capital characters
• holberton.h : Contains header files and function prototypes needed for the program
• man_3_printf : Is a Programmer's Manual for custom printf
• octal_sp.c : Contains a function format_o which perform octa specifier denoted by %o (prints octal value.)
• percent.c : Contains a function format_pers which prints percent sign.
• precision.c : contains four printf functions that perform precision denoted by . followed by an optional decimal digit string(print upto decimal digit)
  • precision : function that checks for d, i, u, o, x, X, c, or s and pass them to their respective function
  • precision_diuc : function that prints d, i, u and c with precision
  • precision_o : function that prints octa with precision
  • precision_xX : function that prints hexa with precision
  • precision_s : function that prints string with precision
• printf.c : Contains two functions that call all the functions within the program
  • _printf : Function that goes through format (String composed of zero ot more characters to print) and prints according to a format
  • func_sp : Function that contains specifiers and corresponding arguments
• signed_sp.c : Contains function format_d which perform integer specifier denoted by %d, or %i (prints signed integer)
• string_sp.c : Contains two fonctions which perform char and str specifier denoted by %c and %s respectively (prints character and string)
  • format_c : Function that prints character
