The Fuel Friend system calculates qty. of fuel to fill

Given:

Pumps need customers to state the exact qty. of fuel to fill

Cars display tank capacity and quantity of fuel still in tank

Drivers like to see the qty. to fill in a unit familiar to them

Drivers, cars, pumps are all free to use any unit of measure

Engineer the Fuel Friend system:

1. Specify a set of requirements and assumptions

2. Design functions to meet the requirements (no OOP)

3. Implement as a command-line pgm in C++ or Java

4. Test that the solution meets the requirements

Requirements: a numbered list with 5-10 items, each item being a paragraph of about 3-5 lines

List assumptions separately if doing so adds clarity

Design: assume procedural programming; no OOP

Draw structure chart to show relationship among functions

Draw flow chart of the logic as if all code is in one function

Implementation: one source file suffices

Develop a command-line pgm which takes no user input

Choose pump, car, and driver units at random. Also pick at random the tank capacity and the qty. of fuel left in tank

Break down the code into meaningful functions

Include clear screenshots from five different runs, each run showing a distinct permutation of units of measure

At least one screen should show the driver and pump using the same unit (say Liters) and the car using a different unit

Turn in five files: requirements, design, source code, test plan with results, and screenshots (all screens in one file)

Test plan: a spreadsheet with 12 columns

Three units of measures: values the pgm chose at random

Tank capacity, qty. left: values the pgm chose at random

Expected qty. of fuel to fill: one for each unit of measure

Reported qty. of fuel to fill: one for each unit of measure

Status: Data rows contains Pass or Fail. See below.

Add one data row for each screenshot turned in

First five columns: copy what the pgm. chose at random

Expected cols: you manually compute using first five cols

Reported cols: copy what the pgm. Reported

Status: Pass iff every reported col equals its expected col
