[Cs3] array/vector initialization with an initializer list

[Mikhail Nesterenko]

CS3 students,

This is per in class discussion.

The rule is that if there is no initialization at all, the array
values are unspecified. If there is initialization, whatever elements
are not given initial values, they are assigned a value of
zero. Hence, a straightforward way to assign zero to every element of
the array is this:

   int a[25] = {0};

In fact, even this zero-initializaiton is legal:

   int a[25] = {}; // although a bit unintuitive
