Printf
Disclaimer
In School 42, almost every project must be written according to a coding syntax standard (also known as "Norme").
That's why some parts may be strange
About
At School 42, we are not allowed to use printf... So let's recode ours! This will be an opportunity to discover a feature of the C - variadic functions - and train us to fine management of display options.
This is the first project of the Algorithms branch at School 42 Paris
