 * Program 10 : Challenge "Use Arrays to Rewrite the 10-bad-baseball.c program"
 * In this fine, I provide a clear solution to the 10-bad-baseball.c program. The 
 * "bad" program uses 18 integer variables to store the scores for 2 baseball teams. 
 * In the c-language, when we want to store numberous elements of data that are related
 * to one another, we use arrays to more uniformly store and access the data.
