A newly-designed electronic gas pump requires a control, Ask an Expert

Engineering

A newly-designed electronic gas pump requires a control program. Using the traditional approach, develop a system flowchart and structure chart, as well as pseudo-code to control the high-level operation. The gas pump has the following typical features:
•LCD display of price and gallons pumped.
•Selection buttons for fuel octane rating (and price).
•LCD dot-matrix display for system messages.
•Keypad and credit-card scanner.
•Thermal printer for receipts.
problem 2
Repeat the system development for the gas pump using the object-oriented approach. Develop a system sequence diagram, any required interaction or collaboration diagrams, as well as a first-cut design class diagram.
problem 3
The gas-pump service technician has a laptop with software designed to query and control the electronic gas pump over a communication link. Develop a series of dialogs that the attendant may encounter when troubleshooting the pump
