ft_printf

Codam [42 Network] project: the aim of this project is to recode the libc function printf.

Project requirements:

• The function prototype should be int ft_printf(const char *, ...); in which the first parameter is the string that should be written to stdout and the second parameter the variable number of arguments.
• It must not do the buffer management like the real printf
• It will manage the following conversions: c s p d i u x X %
• It will manage any combination of the following flags: - 0 . * and minimum field width with all conversions
• You must use the command ar to create your library

Skills:

• Rigor
• Algorithms & AI

Instructions 📋

Clone repo

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

Make

Run make to create the libftprintf.a library.

Compile

gcc libftprintf.a main.c

Include ft_printf in your project

#include "includes/ft_printf.h"

int main () {

	int num = 42;

	ft_printf("Hello, %s\n", "World!");
	ft_printf("Now you can %s %c bunch of %s\n", "use", 'a', "format specifiers");
	ft_printf("The address of num is %p\n", &num);
	ft_printf( "%s%09d\n","Leading zeros: ", 42);
	ft_printf("Precision 42: |%42s|\n", "Fortytwo");
	ft_printf("Lowercase 42 hex: %x\n", 42);
	ft_printf("Uppercase 42 hex: %X\n", 42);
	ft_printf("Minimum length, left-justified: |%-10s|\n", "Hello");
	ft_printf("A string with a minimum length: |%10s|\n", "Hello");
	ft_printf("An asterisk to specify minimum length: |%*s|\n", 10, "Hello");

	return (0);
}

Output

Hello, World!
Now you can use a bunch of format specifiers
The address of num is 0x7ff7bd543588
Leading zeros: 000000042
Precision 42: |                                  Fortytwo|
Lowercase 42 hex: 2a
Uppercase 42 hex: 2A
Minimum length, left-justified: |Hello     |
A string with a minimum length: |     Hello|
An asterisk to specify minimum length: |     Hello|
