The program should be able to keep track of seats in a theatre hall named Bonku. Thre are 22 rows with 15 seats in the theatre. Each seat is uniquely defined by the row and the seat number.
The theatre has three types of customers.
1.Random customer: this one orders one or more tickets on the phone. For each random customer we record name, telephone nummber, together with seat that s\he intends to book.
2.Private Subscriber: this one subscribes one(same) seat in a theatre. For this one we record name, address, telephone number, seat number which he or she subscibes.
3.Corporate Subscriber: this is a company that subscribes more than one(same) seat in the theater hall. For this one we record name of company, address, contact person and telephone number, seats that they have subscribed.
Tips. use records for each subscriber, for the theatre. A two dimentional array for the structure of the hall.
The program must be command based
