/*
This program uses a 2D array seatMap to represent the seat reservation map. Initially, all elements in the seatMap are set to 0, indicating that all seats are available. The reserveSeat function checks if the selected seat is available and reserves it if it is. The displaySeatMap function is used to print the current seat reservation map.

In the main function, a menu is displayed to the user, allowing them to choose the ticket type (first class, business class, or economy class) or to quit the program. The user is then prompted to enter the row number
