Use the template definitions in this chapter to define the following:
An array of string objects
A stack of arrays of double
An array of stacks of pointers to Worker objects
How many template class definitions are produced in Listing 14.18?

The output of the program in Listing 14.18 has one line for each of the 10 elements of twodee, each of which is a five-element array. Each line shows the values, sum, and average of an element of twodee:
1 2 3 4 5 : sum = 15, average = 1.5
2 4 6 8 10 : sum = 30, average = 3
3 6 9 12 15 : sum = 45, average = 4.5
4 8 12 16 20 : sum = 60, average = 6
5 10 15 20 25 : sum = 75, average = 7.5
6 12 18 24 30 : sum = 90, average = 9
7 14 21 28 35 : sum = 105, average = 10.5
8 16 24 32 40 : sum = 120, average = 12
9 18 27 36 45 : sum = 135, average = 13.5
10 20 30 40 50 : sum = 150, average = 15
Done.
