luizlcezario / ft_printf

This is the 3th project of the Ecóle 42, in this project we will recreate the printf with some flags and some convertions!

_{ft_printf of 42. Make with ❤︎ for Luiz Cezario}

🚀 Introduction to ft_printf

This is the third project in the 42 Cadet Curriculum. This project is pretty straight forward, recode the printf function. The versatility of the printf function in C represents a great exercise in programming for us. This project is of moderate difficulty. It will enable you to discover variadic functions in C. The key to a successful ft_printf is a well-structured and good extensible code.

Prototype

int ft_printf(const char *, ...); - This is copy of the otiginal printf.

int ft_formatf(const char *, ...); - This is a function that return the string formated.

📋 Conversions & Flags & Expected Order

Conversion	Description	Project
c	Single ascii character	Mandatory
s	String of characters NULL terminated	Mandatory
p	Pointer location converted to hexadecimal value	Mandatory
d	Decimal number	Mandatory
i	Integer in decimal base	Mandatory
u	Unsigned integer in decimal base	Mandatory
x	Unsigned number printed in lowercase hexadecimal base	Mandatory
X	Unsigned number printed in uppercase hexadecimal base	Mandatory
%	The '%' ascii character	Mandatory

Flag	Description	Project
-	Left align the argument passed	Bonus 1
0	Add '0' as a padding character in numeric conversions (single space is default)	Bonus 1
.	Precision definition, followed by a number	Bonus 1
+	Add a plus sign ('+') in the front of positive numeric conversions	Bonus 2
' '	Add a single space (' ') in the front of positive numeric conversions	Bonus 2
#	Add the corresponding prefix in front of x, X and o conversions	Bonus 2

Holder key	Prefix and justification flags *	Minimum Width *	Precision *	Conversion
%	- , 0 , + , ...	10, 5 , ...	., .10, .5, ...	c, d, i, s, ...

Some help for those who are doing

In the Picture Below you will see the campatibility of the convertion types with the flags

👷 How to Test

# Clone the Repo.
$ git clone https://github.com/luizlcezario/ft_printf.git

# Enter in the Folder.
$ cd ft_printf

# for testing the printf and the formatf, modify the main file and than run the comand.
$ make teste

# now you will see a a.out file run than and see your tests.
$ ./a.out
