ft_printf

ft_printf is a C project that aims to recreate the C standard library function printf(). This project is part of the 42 coding school curriculum and helps students understand variadic functions, string manipulation, and memory management in C.

Features

• Supports basic format specifiers: %c, %s, %p, %d, %i, %u, %x, %X, %n.
• Handles flags: -, 0, . and *.
• Handles field width and precision.
• Implements a custom buffer for efficient output.

Getting Started

Prerequisites

• A Unix-based operating system (macOS, Linux, or WSL on Windows)
• GCC compiler
• make utility

Installation

1. Clone the repository:

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

2. Change into the project directory:

cd ft_printf

3. Compile the project using the provided Makefile:

make

Usage

1. Include the header file ft_printf.h in your C source files where you want to use the ft_printf function.

#include "ft_printf.h"

2. Use the ft_printf function in the same way as the standard printf() function. Here's an example:

#include "ft_printf.h"

int main(void)
{
    int number = 42;
    char *string = "Hello, World!";

    ft_printf("This is an integer: %d\n", number);
    ft_printf("This is a string: %s\n", string);

    return 0;
}

3. Compile your program with the ft_printf object files:

gcc -Wall -Wextra -Werror -I./ -o your_program your_program.c libftprintf.a

4. Run your program:

./your_program

Testing

The project comes with a test suite. To run the tests, follow these steps:

1. Compile the test program:

make test

2. Run the test program:

./test_ft_printf
