Stuck in function and booleans

Question

I have function called firstRun(), inside of it I have two defined booleans filesDeleted and dirsDeleted.

Also inside in function

Answer 1

Change your

bool filesDeleted;
bool dirsDeleted;

to

bool filesDeleted = false;
bool dirsDeleted = false;

These are local variables and they must be assinged before use them.

From 5.1.7 Local variables

A local variable is not automatically initialized and thus has no default value. For the purpose of definite assignment checking, a local variable is considered initially unassigned.

Answer 2

Unlike class member variables, local variables in methods do not have a default value, and must be definitely assigned before you try and read from them:

so you need to use

bool fileDeleted = false;
bool dirsDeleted = false;

instead of

bool filesDeleted;
bool dirsDeleted;
