With all due respect to the person responsible for alligators in Ada, 
the C++ example showed 2 independent arrays, the sizes of which were 
known at the point of creation. For such an example, the use of local 
scopes to declare the arrays is probably safer and faster than messing 
around with pointers. Certainly there are times when an array needs to 
be resized, but this example isn't one of them.
