HW#9
 Due Wednesday, 10/10/7, hw9.cpp

Write a program that reads in 10 floats from the user.
Make sure to write this program appropriately so that you
can change the number from 10 to 30 very easily (by changing
one const int variable).

After you have read in the floats, your program should sum the 
numbers in the array.

Once you have computed the sum, output each element of the array
followed by the sum. An example output could look like:

The sum of 1, 2, 37.3, -37.3, 7.4, -7.4, 5, 6, 10, and 1 is 25.
