Introduction

This project involves recreating the libc's printf() function. This will introduce you to variadic functions in C, a critical skill for handling functions that accept an indefinite number of arguments. Implementing this function will help you understand more about handling different data types and formatting output.

Common Instructions

• The project must be coded in C and conform to the coding norm.
• Handle memory properly - no leaks are tolerated.
• Submit a Makefile that compiles your project with appropriate flags and does not relink.
• Do not implement buffer management like the original printf().

Mandatory Part

Your implementation of ft_printf() must handle the following conversions: c, s, p, d, i, u, x, X, and %.

• %c Prints a single character.
• %s Prints a string.
• %p Prints a void * pointer in hexadecimal format.
• %d and %i Print a signed integer in base 10.
• %u Prints an unsigned decimal (base 10) number.
• %x Prints a number in hexadecimal (base 16) lowercase.
• %X Prints a number in hexadecimal (base 16) uppercase.
• %% Prints a percent sign.

Bonus Part

For those who complete the mandatory part perfectly, the bonus part includes handling flags and minimum field widths under all conversions.

• Flags: '-', '0', '.', '#', '+', and ' '(space).

Compilation

Compile the library using the Makefile provided, ensuring all rules like all, clean, fclean, and re are present to manage the library properly.
