> This is a reimplementation of the function printf included in libc. 

> This implementation cover the following set of flags and conversions, 

> besides the availability of the width and precision modifiers.

### Flags

| Flag    | Description                                                                   |

|-------  |-------------------------------------------------------------------------------|

| **-**   | Left-justify within the given field width; Right justification is the default.|

| **0**   | Left-pads the number with zeroes(0) instead of space.                         |

| **+**   | Add a plus sign '+' int the front of positive numeric conversions             |

|  ` `    | If no sign is going to be written, a blank space is inserted before the value.|

| **#**   | Used with x or X specifiers. Add (0x) in front of values different than zero. |

| **num** | Number between % and the specifier is the minimum field width                 |

| **.**   | precision                                                                     |

### Conversions

| Specifiers | Description                                            |

|------------|--------------------------------------------------------|

|    **c**   | Print a single character.                              |

|    **s**   | Print a string of characters                           |

|    **p**   | The void * pointer argument is printed in hexadecimal. |

|    **d**   | Print a decimal (base 10) number.                      |

|    **i**   | Print an integer in base 10.                           |

|    **u**   | Print an unsigned decimal (base 10) number.            |

|    **x**   | Print a number in hexadecimal (base 16)                |

|    **%**   | Print a percent sign '%'                               |

> For the specifier d and i, the precision is the minimum number of digits to be print.  

> For the specifier s, the precision is the maximum field width.  

> Stay tuned when:

> * Flag '0' is ignored when flag '-' is present.  

> * Flag '0' is ignored when flag '.' is present (%d e %i)  

> * Flag '0' result in undefined behavior with specifier c, s and p  

> * FLag '.' result in undefined behavior with specifier c and p  

>   

> Syntax to use printf:  

`%[flag][min-width].[precision][length modifier][conversion specifier]`
