Printf ALX Group Prject

C programming for ALX School!

==================================================================================

_printf is a custom implementation of the C programming function printf. This project is an application of the C programming knowledge that Holberton School cohort 3 students have learned since starting the program on May 1, 2017.

synopsis The objective of the printf project is to learn the base functionality of printf, take those concepts and apply them ourselves to create a new printf that works in the same way. Enviroment our printf project has been teasted on ubuntu 20.04 LTS Prototype: int _printf(const char *, ...);

Examples String

Input: _printf("%s\n", 'This is a string.'); Output: This is a string. Character

Input: _printf("The first letter in the alphabet is %c\n", 'A'); Output: The first letter in the alphabet is A Integer

Input: _printf("There are %i dozens in a gross\n", 12); Output: There are 12 dozens in a gross

Decimal Input: _printf("%d\n", 1000); Output: 1000

Project Requirements All files will be compiled on Ubuntu 20.04 LTS Programs and functions will be compiled with gcc 4.8.4 using flags -Wall -Werror -Wextra and -pedantic Code must follow the Betty style Global variables are not allowed Authorized functions and macros: write (man 2 write) malloc (man 3 malloc) free (man 3 free) va_start (man 3 va_start) va_end (man 3 va_end) va_copy (man 3 va_copy) va_arg (man 3 va_arg)

Mandatory Tasks Write function that produces output with conversion specifiers c, s, and %. Handle conversion specifiers d, i. Create a man page for your function. Advanced Tasks Handle conversion specifier b. Handle conversion specifiers u, o, x, X. Use a local buffer of 1024 chars in order to call write as little as possible. Handle conversion specifier S. Handle conversion specifier p. Handle flag characters +, space, and # for non-custom conversion specifiers. Handle length modifiers l and h for non-custom conversion specifiers. Handle the field width for non-custom conversion specifiers. Handle the precision for non-custom conversion specifiers. Handle the 0 flag character for non-custom conversion specifiers. Handle the custom conversion specifier r that prints the reversed string. Handle the custom conversion specifier R that prints the rot13'ed string. All above options should work well together. #Repository Contents The repository contains the following files FILE Description printf.c printf a file containing the _printf function and get function holberton.h contains function and struct declarations inttostr.c holds functions which converts integers to strings help_funcs.c contains functions of printers help_funcs_2.c contains functions of printers README.md contains this help description man_3_printf contains manual of this functions
