The output from the program is shown here:

10 9 8 7 6 5 4 3 2 1 0

20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

4 3 2 1 0

To compile this program, you must include both the preceding code and the code 

contained in the 

Counter

 namespace. Assuming you called the preceding code 

NSDemo.cs

and put the source code for the 

Counter

 namespace into a file called 

Counter.cs

 as 

mentioned earlier, then you can use this command line to compile the program:

csc NSDemo.cs counter.cs

Some important aspects of this program warrant close examination. First, since
