About

This project, "ft_printf," is part of the 42 School curriculum and aims to re-implement the standard C library function printf(). The project focuses on understanding variadic functions, parsing, and formatting output.

Installation

To compile the ft_printf library, run the following commands:

1. Clone this repository:

git clone https://github.com/your_username/ft_printf.git

2. Include the ft_printf.h header file in your C file.
3. Compile your program with:

make

This will generate the libftprintf.a library, which you can link with your C programs as mentioned in the usage section.

Usage

To use the ft_printf function in your C program, here's an example of how to use it in your code:

#include "ft_printf.h"

int main() {
    ft_printf("Hello, %s!\n", "world");
    return (0);
}

Functionality

The ft_printf function supports a subset of the format specifiers used by the standard printf() function. Supported format specifiers include:

• %c for characters
• %s for strings
• %d and %i for integers
• %u for unsigned integers
• %x for hexadecimal numbers (lowercase)
• %X for hexadecimal numbers (uppercase)
• %p for pointers
• %o for octal numbers
• %% for the percent sign
