baseball.cpp

this program gets integer data from a file in the following repetitive format:

player#, hits, walks, outs.

The program declares arrays for each, calculates batting average based on that data,

then prints out the player number, batting average and total walks per player.

The user has to make a file with twenty players in the order declared above (make

sure there is whitespace between each entry!)
