Correct.  I was making the assumption that the discussion was not about
static variables.  Static variables are always initialized:

static int a;

will be zero

static char b;

will be NULL

static bool c;

will be set to false (0) unless zero is defined as TRUE.

However, if you want a particular result, it is always best to
initialize the variables you are going to use.
