What's the difference ? By default the variable set itself to a default value

@maushax that's why you always compile with -Werror 👍

In C / C++, the variable will be initialised only if it's a global variable. A local variable will not be initialised, and it's actually bad practice to initialise everything "just in case".

And "not initialized" means that it well be some valid but unpredictable integer. Not null or undefined that you have in other languages :]

@Lensflare even better, if it's undefined anyway, the compiler can choose the fastest "undefined" and just optimise that shit away. Ideally the whole program.
