In C++

Objectives

Implementing a class

Using a header file

Design a small inheritance tree

Map your classes to the tree

Tasks

For this project you are going to create a class that represents a manufactured part on a bill of material (BOM). This part will have the following attributes (represented as a private variable):

identifier - The parts identifier as an alpha numeric string

drawing - The AutoCAD drawing file that represents the part

quantity - The number of parts that are required

In addition to the above attributes your class will provide the following methods.

Part(string id, string dwg, int qty) - Object constructor: Initializes member variables

getId() - returns the id of the part

void setId(string id) - sets the id of the part

string getDrawing() - returns this parts drawing file name

void setDrawing(string drawing) - sets this parts drawing name

int getQuantity() - returns the quantity of this part

void setQuantity(int qty) - sets the quantity of this part

string toString() - returns a string representation of the part

Your task is to design a class named Part you will declare the class in a file Part.h and implement the class in Part.cpp. The main function is already written for you below, do not modify the main function.

#include #include "Part.h" using namespace std; //Do not modify this file int main(int argc, char **argv) { //Constructs a new part Part p("12-00001","12-00001.dwg",1); //Print the part out. cout << p.toString() << endl; //Test our set Drawing method p.setDrawing("14-11111.dwg"); cout << p.toString() << endl; //Test our set setId method p.setId("my_new_id"); cout << p.toString() << endl; //Test our set Quantity method p.setQuantity(42); cout << p.toString() << endl; //Test each of the accessor methods cout << p.getDrawing() << endl; cout << p.getId() << endl; cout << p.getQuantity() << endl; return 0; }

SAMPLE OUTPUT

Id: 12-00001 drawing: 12-00001.dwg qty: 1 Id: 12-00001 drawing: 14-11111.dwg qty: 1 Id: my_new_id drawing: 14-11111.dwg qty: 1 Id: my_new_id drawing: 14-11111.dwg qty: 42 14-11111.dwg my_new_id 42

PART H

#ifndef PART_H #define PART_H #include using namespace std; class Part { private: string m_id; string m_drawing; int m_quantity; public: Part(string id, string dwg, int qty); string getId(); void setId(string id); string getDrawing(); void setDrawing(string drawing); int getQuantity(); void setQuantity(int qty); string toString(); }; #endif

Part cpp

// Part.cpp : Defines the entry point for the console application. // #include #include "Part.h" using namespace std; // // I will use my own 'main' file; therefore, you can modify // this file as you see fit. // int main(int argc, char **argv) { //Constructs a new part Part p("12-00001", "12-00001.dwg", 1); //Print the part out. cout << p.toString() << endl; //Test our set Drawing method p.setDrawing("14-11111.dwg"); cout << p.toString() << endl; //Test our set setId method p.setId("my_new_id"); cout << p.toString() << endl; //Test our set Quantity method p.setQuantity(42); cout << p.toString() << endl; //Test each of the accessor methods cout << p.getDrawing() << endl; cout << p.getId() << endl; cout << p.getQuantity() << endl; return 0; }
