Objectives

  • Design an abstract data type.
  • Learn how to use object-oriented and top-down design techniques.
  • Implement an abstract data type using a C++ class.
  • Incorporate user-friendly input/output.
  • Demonstrate input editing and error-checking criteria.
  • Demonstrate quality, efficiency and accuracy of program coding.

Description

For project 1 you will need to create a vehicle class that will store information about a single vehicle. Vehicles are identified by a model (maximum 20 characters), price (non-negative double), and the manufacturer's name and location. Manufacturer's name and location should not exceed 15 characters each.

Your program should create a menu interface that has the following options:

  • Enter the information for a vehicle.
  • Display the information for the vehicle.
  • Exit the program.

Permit the user to enter multiple vehicles, though the program will only maintain and display information about the most recently entered vehicle.

Note: Though a string class exists, for this project I want you to represent all strings as char arrays.

The vehicle class should look like:

const int MAX_MODEL = 20; const int MAX_NAME = 15; const int MAX_LOCATION = 15; class Vehicle { public: Vehicle(char mdl[] = "", double pr = 0, char nm[] = "", char loc[] = ""); // Pre-condition: mdl cannot be longer than 20 characters, // nm and loc cannot be longer than 15 characters, // pr must be non-negative // Post-condition: If mdl, nm, or loc exceed length, they will be truncated. // mdl, nm and loc will be stored in model, name and location, // respectively. If pr is // negative, 0 will be stored in price; otherwise pr will be stored in price void setVehicle(char mdl[] = "", double pr = 0, char nm[] = "", char loc[] = ""); // Pre-condition: mdl cannot be longer than 20 characters, // nm and loc cannot be longer than 15 characters, // pr must be non-negative // Post-condition: If mdl, nm, or loc exceed length, they will be truncated. // mdl, nm and loc will be stored in model, name and location, // respectively. If pr is // negative, 0 will be stored in price; otherwise pr will be stored in price void display() const; // Pre-condition: None // Post-condition: model, price, name and location will be displayed on a single line // Other functions as needed private: char model[MAX_MODEL + 1]; double price; char name[MAX_NAME + 1]; char location[MAX_LOCATION + 1]; };

Note: Implementation of the program is not sufficient for the maximum grade. I will be grading the quality, efficiency and accuracy of your program code.
