0x10. C - printf

Description

This team project is part of the first year curriculum of Holberton School. _printf replicates the C standard library printf() function.

What you should learn from this project:

• How to use git in a team setting
• Applying variadic functions to a big project
• The complexities of printf
• Managing a lot of files and finding a good workflow

Prototype

int _printf(const char *format, ...);

Usage

• Prints a string to the standard output, according to a given format
• All files were created and compiled on Ubuntu 14.04.4 LTS using GCC 4.8.4 with the command gcc -Wall -Werror -Wextra -pedantic *.c
• All files were linted for syntax and style with Betty
• Returns the number of characters in the output string on success, -1 otherwise
• Call it this way: _printf("format string", arguments...) where format string can contain conversion specifiers and flags, along with regular characters

Examples

• _printf("Hello, Holberton\n") prints "Hello, Holberton", followed by a new line
• _printf("%s", "Hello") prints "Hello"
• _printf("This is a number: %d", 98) prints "This is a number: 98"

Files

The primary file being utilized is _printf.c, which contains the _printf function itself. This file is linked to a header file named holberton.h, as well as function prototypes for:

_puts.c _rot13.c _print_number.c _strlen.c _print_binary.c _putchar.c _rev_string.c

A man page has been included, called: man_3_printf
