Implementation of Printf in C

This is a simple implementation of the printf function in C. It is a project for ALX curriculum.

Usage

The function is called _printf and it takes a format string and an arbitrary number of arguments. The format string is a string that contains zero or more directives. Each directive is introduced by a percent sign (%) and ends with a conversion specifier. The conversion specifier is a character that specifies the type of conversion to be applied. The _printf function writes output to stdout, the standard output stream.

The _printf function returns the number of characters printed (excluding the null byte used to end output to strings).

Format Specifiers

The following conversion specifiers are supported:

Specifier	Output
c	Character
s	String of characters
%	Percent sign
d	Signed decimal integer
i	Signed decimal integer
b	Unsigned binary
u	Unsigned decimal integer
o	Unsigned octal
x	Unsigned hexadecimal integer (lowercase)
X	Unsigned hexadecimal integer (uppercase)
S	String of non-printable characters (preceded by \x)
p	Pointer address
r	Reversed string
R	Rot13 string

Compilation

The _printf function is compiled with the following command:

gcc -Wall -Werror -Wextra -pedantic *.c

a.out

Example

_printf("Let's try to printf a simple sentence.\n");
_printf("Character:[%c]\n", 'H');
_printf("String:[%s]\n", "I am a string !");

Output

Let's try to printf a simple sentence.
Character:[H]
String:[I am a string !]
