ft_printf is a custom implementation of the standard printf function in C. It allows formatted output with various format specifiers and handles multiple data types. This project is part of the 42 School curriculum.

Usage

To use ft_printf, clone the repository in the root of your project using one of the following commands:

SSH

git clone [email protected]:blueyaGIT/ft_printf.git

HTTPS

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

GitHub CLI

gh repo clone blueyaGIT/ft_printf

This will create a directory called ft_printf/. Enter it with the command:

cd ft_printf

Compiling

ft_printf is provided in .c and .h files, which you can include in your project. To compile a test program, you can use:

gcc -Wall -Wextra -Werror ft_printf.c ft_printf_utils.c main.c -o printf

Example Usage

#include <stdio.h>
#include "ft_printf.h"

int main(void)
{
    int value = 42;
    ft_printf("Hello, World! Value: %d\n", value);
    return (0);
}

Files

• ft_printf.c - Contains the ft_printf() function implementation.
• ft_printf.h - Header file with function prototypes and necessary includes.
• ft_*.c - Utility functions used by ft_printf().

Function Description

int ft_printf(const char *format, ...);

Formats and prints data to the standard output based on format specifiers.

• Returns the number of characters printed (excluding \0).
• Supports format specifiers such as %c, %s, %d, %i, %u, %x, %X, and %p.

Notes

• Ensure proper handling of variable arguments to avoid undefined behavior.
• The function is designed to mimic standard printf but does not support all its features.
• Memory allocation is not required unless additional dynamic operations are introduced.
