title: DATA
title: DATA
etc...
which is...

Is that even possible ?
Lets say that the code has a lot of scanf lines. Instead of manually running and adding values by hand when debugging, is it possible to "feed" stdin with data so that when the scanf starts reading, it will read the inputted data...

But if you write a test program you'll find that
