* Purpose: 1D array practice exercises
* NOTE: this is often thought to be the most difficult of the five.

* Sample Output:
*** start of 27610_Arrays03.cpp program ***
Number Count
1 1

3 5
4 2
5 3
*** end of 27610_Arrays03.cpp program ***
Input:
No data comes from the keyboard; all data, including the data
for the array, are contained within the program.
An integer array of 13 numbers: 3, 4, 5, 3, 2, 1, 3, 4, 5, 3, 2, 3, 5
An integer array of 5 counts intialized to all 0.
Compile-time arrays with initialization list of numbers.
NOTE: In main() function
Processing:
TODO #1: in the main() function,
complete the coding of the numbers array
TODO #2: in the main() funciton,
complete the coding to call the countValues() function
The values in the numbers array are counted
and the correct cells of the count array are increment.
Output:
TODO #3: in the main() funciton,
complete the coding to call the display() function,
Display as shown in sample output.
Use iomanipulators to format output
After the main() function
TODO #4: code the display() function
TODO #5: code the countValues() function
