#Exploring the C programming language - Rewrite Printf

Description

This project creates our version, _printf, of the C library function printf. Printf formats data and converts it to a character string and outputs to stdout.

##How To Use

$ git clone git@github.com:j-tyler/printf.git
$ gcc -Wall -Werror -Wextra -pedantic *.c

Compile everything within the directory and use _printf in your code.

###Declaration int _printf(const char *format, ...)

###Example

_printf("My %s is %d", "favorite number", 8);
$ My favorite number is 8

##Completed Features

###Format tags format tags must follow the format of [flags][width][.precision][length]specifier

specifier	output
c	characters
s	string of characters
i or d	signed decimal int
u	unsigned decimal int
o	signed octal
x	unsigned hexadecimal int
X	unsigned hexadecimal int (Upper Case)
b	Binary
p	pointer address

Flags	Effected Specifers	Description and Examples
-	d, i, u, o, x, X, b, c, s	Left justify _printf("A%3dlast", 5); _printf("A%-3dlast", 5); output $ A 5last $ A5 last
+	d, i	Forces proceed to with a sign even if positive _printf("A%dlast", 5); _printf("A%+dlast", 5); output $ A5last $ A+5last
(space)	d, i	if no sign is given, proceed with space _printf("A%dlast", 5); _printf("A% dlast", 5); output $ A5last $ A 5last
#	o, x, X	Used with o, x or X specifiers the value is preceded with 0, 0x,or 0X respectively for values different than zero. _printf("%o, 1"); _printf("%#o, 1"); output $1 $01
0	d, i, u, o, x	left pad with spaces with 0 _printf("A%3dlast", 5); _printf("A%03dlast", 5); output $ A 5last $ A005last

width	Effected Specifers	Description and Examples
-	d, i, u, o, x, X, b, c, s	minimum number to be printed _printf("A%dlast", 5); _printf("A%3dlast", 5); output $ A5last $ A 5last

.percision	Effected Specifers	Description and Examples
-	d, i, u, o, x, X, s	For integer specifiers (d, i, o, u, x, X) − precision specifies the minimum number of digits to be written. If the value to be written is shorter than this number, the result is padded with leading zeros. _printf("A%dlast", 5); _printf("A%.3dlast", 5); output $ A5last $ A005last For s − this is the maximum number of characters to be printed. _printf("A%s", "Holberton"); _printf("A%.3s", "Holberton"); output $ Holberton $ Hol

##Future features format tags -, +, (space), #, and width for the pointer flag implement the length format tags
