Wow, I didn't know that uninitialized variables were set to zero
automatically in C++.
However, a quick test with the GCC shows that only global variables are
automatically initialized; local variables are not.
Interestingly, I was taught that in C++, built-in types had a "constructor"
that you could call like this:
int* p = new int();
In these cases, according to what I learned, the parentheses call the
"constructor" to be called, initializing the variables to zero. HOWEVER,
the GCC didn't accept the syntax.
I would also note that, with the GCC, all ints allocated using "new" are
automatically initialized to zero.
But let me finish by saying that depending on automatic intialization is a
really bad idea.
