A theatre seating chart is implemented as a two-dimensional array of ticket prices, like this: AISLE ROW 1 2 3 4 5 6 7 8 9 10 -------------------------------------------------------------------------------------------------------------- 10 10 10 10 10 10 10 10 10 10 10 9 10 10 10 10 10 10 10 10 10 10 8 10 10 10 10 10 10 10 10 10 10 7 10 10 20 20 20 20 20 20 10 10 6 10 10 20 20 20 20 20 20 10 10 5 10 10 20 20 20 20 20 20 10 10 4 20 20 30 30 40 40 30 30 20 20 3 20 30 30 40 50 50 40 30 30 20 2 30 40 50 50 50 50 50 50 40 30 1 30 40 50 50 50 50 50 50 40 30 Write a program that prompts users to pick either a seat or a price. Mark sold seats by changing the price to 0. When a user specifies a seat, make sure it is available. When a user specifies a price, find any seat with that price starting at the front and working to the back of the theatre. Make sure you write your program using well defined functions. You are to hand in: Source code (well documented) Input file (if used) Sample tests for valid and invalid choices Hierarchy Chart User Guide
