0x11 -> Printf

Description

printf is a weel known function used in C programming to do formated printing. Usually it only takes the standard library to call it into a c program, and using it for simple strings or formatted specifiers that allow us to print diferent types of data. This time we are presenting a printf project made from scratch in most of its features in order to understand the complexity of a powerful tool. You can see man 3 of printf to understand how _printf works.
