About

The ft_printf library provides a function that mimics the behavior of the original printf function in the C standard library. It is designed to handle various conversion specifiers allowing users to print formatted output to the standard output stream.

Features

Mimics the behavior of the original printf function.
Supports the following conversion specifiers:
- %c: Prints a single character.
- %s: Prints a string (as defined by the common C convention).
- %p: Prints a void pointer argument 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

To create the library, run the following command after cloning:

cd ft_printf && make

To test the library, compile your test code along with the ft_printf library as follows:

cd .. && cc -Wall -Wextra -Werror main.c ft_printf/ft_printf.a && ./a.out
