ft_printf()

This project involves reimplementing the printf() fucntion in C by creating ft_printf(). This task provides an opportunity to explore variadic functions and enhance programming skills.

The goal is to create a library named libftprintf.a, which inculdes the ft_printf() function capable of handling various conversions such as characters, strings, pointers, integres, and more. The implementation does not require replication the original printf()'s buffer management system.

It's a funny project to improve my skills in C.

Format specifiers Reference

• %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.

Demonstration

create a main.c

Example of main.c

#include "ft_printf.h"

int main()
{
	ft_printf("Hello world number %d !\n", 5);
}

Output

$> make
$> gcc main.c libftprintf.a
$> ./a.out
Hello world number 5 !
