Introduction

Ft_printf is a project from the common core curriculum of 42 school. The goal of this project is to code a clone of the libc library printf(). The printf() function in C is a widely used function for formatted output. It stands for "print formatted" and is primarily used to display data on the screen or write it to a file. The function takes a format string as its first argument, which can contain placeholders called format specifiers. These placeholders are replaced by the values of additional arguments provided to the function.

• Returns the number of characters printed, excluding the null byte used to terminate output to strings.

The code was written according to the 42 norm guidelines(norminette).

Usage

1. Clone the repository

git clone git@github.com:amauricoder/42_ft_printf.git

2. Do make to compile the files

make

This will generate a libftprintf.a file in the root folder, this is the library containing the ft_printf().

3. Go to your header file and include the library

# include "ft_printf.h"

4. Syntax Example

  ft_printf("This is a syntax usage example.\n Followed by a number %i.", nbr);

Obligatory convertions

Those are the obligatory conversions requirements of the project - for more detail, check the subject:

• %c Prints a single character.
• %s Prints a string (as defined by the common C convention).
• %p The void * pointer argument has to be printed 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.

Makefile Overview

In this project, the Makefile offers the following essential rules:

• make: Compiles the project to libftprintf.a.
• make clean: Cleans the directory by removing .o files, preserving libftprintf.a.
• make fclean: Completely cleans the directory by deleting both .o files and libftprintf.a.
• make re: Refreshes libftprintf.a by recompiling everything.

Stop deceiving yourself. Mere ability to copy code doesn't enhance your skills. This is outside the scope of school purposes. Everyone can be a "copy paster," but not everyone can be a programmer. Good luck!
