operator[] (int i) [Vector template]

Peek at item i in the vector (zero-based) using operator[] instead of at(). Only call this if the item exists.

When used on the left side an expression, sets the value at that location. The array must already contain that element; you cannot increase the size of the array using operator[].

T& operator[](int i);
const T& operator[](int i) const;

Vector<int> v({123, 456, 789});"%d", v[0]);
v[0] = 999;
