Chapter 4, Problem 4.2E
Program Plan Intro
Given Information:
In an automated railway ticket-issuing system, users need to select their destination and input a credit card and a personal identification number. A menu display of potential destinations is activated, along with a message to the user to select destination after the user presses the start button when the rail ticket is issued. Users are requested to input their credit card after a destination has been selected and the validity of credit card is validated and the user is then requested to input a personal identifier and if validated then ticket is issued.

Ticket-issuing system:
An automated ticket machine sells Airline tickets. Users select their destination and input a credit card and a personal identification number. The Airline ticket is issued and their credit card account charged. When the user presses the start button, a menu display of potential destinations is activated, along with a message to the user to select a destination and the type of ticket required. Once a destination has been selected, the ticket price is displayed, and customers are asked to input their credit card. Its validity is checked, and the user is then asked to input his or her personal identifier (PIN). When the credit transaction has been validated, the ticket is issued.

The light changes as per the sequence listed below: A. Before switch ON, all 4 roads should get ‘flashing yellow’ so as to enable them to look around and cross the road junction. B. When switched ON, Main roads 1 & 3 should get green signals G1/G3 to go straight. This signal remains on for 30 seconds. C. The above signals should be changed over to go right GR1/GR3 for 15 seconds only if any sensor S1/S3 of vehicles waiting to turn right is detected in the right turn lane . This will take place after a brief yellow signals Y1/Y3 in between. D.
