## 💡 About the project

> The aim of this project is to re-code ``` libc ```'s printf function with the conversions:


' c ', ' s ', ' p ', ' d ', ' i ', ' u ', ' x ', ' X ' and ' % '.




**Requirements** 

• The function has to handle the following conversions: cspdiuxX% 

• The function will be compared against the original printf() 

• To create the library command ar must be used 

• Don’t implement the buffer management of the original printf() 

• Using the libtool command is forbidden 

• Executable libftprintf.a has to be created at the root of your repository 

**Key learning points**

  - Handling variadic arguments

  - Organising a complex project with various sub-functions & libraries in sub-directories

## 🌁  Format specifiers explained

| Specifier	| Meaning																|

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

| * [`c`]	| Prints a single character   				   							|

| * [`s`]	| Prints a string (as defined by the common C convention) 				|

| * [`p`]	| The void * pointer argument has to be printed in hexadecimal format   |

| * [`d`]	| Prints a decimal (base 10) number 									|

| * [`i`]	| Prints an integer in base 10											|

| * [`u`]	| Prints an unsigned decimal (base 10) number							|

| * [`x`]	| Prints a number in hexadecimal (base 16) lowercase format				|

| * [`X`]	| Prints a number in hexadecimal (base 16) uppercase format				|

| * [`%`]	| Prints a percent sign 												|

## 🛠️ **Usage**

Clone the repository:

```bash
