ft_printf

For the ft_printf project of the 42 school cursus, we must recreate the famous C library printf function. This project teaches us about variadic arguments as well as structures if we plan to implement printf's extra flags.

• Supported conversions: %, c, s, p, i, d, u, x, X

Status

Finished: 2024-11-27. Grade: 100/100.

Usage

make to compile.

Basic Usage

For example, let's create a main.c file.

// Include the header
#include "ft_printf.h"

int main(void)
{
      // Call the function
      ft_printf("Testing ft_printf! %d", 42);
      ft_printf("Testing ft_printf! %X", 255);
      return (0);
}

Compile the main.c file with the ft_printf library and run the program:

gcc main.c libftprintf.a && ./a.out

Output should be:

Testing ft_printf! 42
Testing ft_printf! FF

Advanced Usage: Format Specifiers

The table below lists supported format specifiers:

Specifiers
Format Specifier	Description
%	% followed by another % character writes % to the screen.
c	writes a single character.
s	writes a character string.
p	writes an implementation-defined character sequence defining a pointer address.
d or i	writes a signed integer to decimal representation.
u	writes an unsigned integer to decimal representation.
x or X	writes an unsigned integer to hexadecimal representation.
