42_printf

The goal of this project is pretty straightforward. You will recode printf(). You will mainly learn about using a variable number of arguments. How cool is that?? It is actually pretty cool :)

Check my article about this project:

Grade

1. Challenges

The biggests challenges in ft_printf recode function, in my opinion, are three:

1. Understanding variadic functions (functions that receives an variable number of arguments);

• https://en.wikipedia.org/w/index.php?title=Variadic_function&oldid=1172763047

• https://www.geeksforgeeks.org/variadic-functions-in-c/

2 . Understanding stdarg.h library, create structs witch contains pointers to the arguments received, and implement the logic depending in each kind of variable argument type;

3 . Last but not least, understand about conversion, flags, width precision and cspdiuxX%.

I created a board to help undestanding

• https://man7.org/linux/man-pages/man3/printf.3.html

2.2 Organize your schedule;

2.3 Test a LOT!
