Drunk Walker Program

[johnprovostmusic1]

So - Just a warning - this is a big question and will require me to post a lot of code. I'm working on a program called drunk walker. It starts as an array of periods. The user enters a row and column to start the "drunk walker." Then he moves around randomly, leaving the alphabet in his trail until he blocks himself in or comes to the end of the alphabet. My code will compile right now, but I cannot get the switch section of it to run at all. I'm wondering what I'm missing in order for it to at least run the switch and print out the second array? Any support is appreciated.

Your program does enter the switch statement but then gets stuck there forever, because the only way it can exit (the while loop) is if alphaIndex equals 26. You initialize this to 0 at the beginning of your program but then never do anything else with it so that condition is never met.
