/*File:  Array01.cpp
This C++ program illustrates the use of a simple
one-dimensional array in C++. 

The program asks the user to enter five integer
values in succession.  It stores the values in
reverse order in an array.  Then it displays the
contents of the array in forward order.

Then it computes and displays the average of the
values stored in the array, the minimum value
stored in the array, and the maximum value 
stored in the array.

The program displays the following output on the
screen for a typical set of input data:

Enter an integer value: -100
Enter an integer value: -50
Enter an integer value: 0
Enter an integer value: 49
Enter an integer value: 99
Array contents:
99 49 0 -50 -100
Average: -0.4
Minimum: -100
Maximum: 99
