10.18 LAB: Plant information (vector)

Given a base Plant class and a derived Flower class, complete main() to create a vector called myGarden. The vector should be able to store objects that belong to the Plant class or the Flower class. Create a function called PrintVector(), that uses the PrintInfo() functions defined in the respective classes and prints each element in myGarden. The program should read plants or flowers from input (ending with -1), adding each Plant or Flower to the myGarden vector, and output each element in myGarden using the PrintInfo() function.

Ex. If the input is:

plant Spirea 10
flower Hydrangea 30 false lilac
flower Rose 6 false white
plant Mint 4
-1

the output is:

Plant Information:
   Plant name: Spirea
   Cost: 10

Plant Information:
   Plant name: Hydrengea
   Cost: 30
   Annual: false
   Color of flowers: lilac

Plant Information:
   Plant name: Rose
   Cost: 6
   Annual: false
   Color of flowers: white

Plant Information:
   Plant name: Mint
   Cost: 4

Answer 1

Language upon which implemented : Visual C++

IDE/Editor used : Visual Studio

Summary : Hi Student. As per your code and logic, I have developed a nice menu driven Base program in order to add Garden details and print Garden Details. Rest All things are almost same, I have moved the Add Details to a separate method AddToGarden for the sake of modularity.

Code :

Note : You can run the below mentioned Main.cpp (the main logic) file taking your own compiler. But if you want to run this program in visual studio perfectly, yo need to edit the various files. The small changes, done, are discussed below :

0. Add a new file named stdafx.h which has following code :

#pragma once

#include <SDKDDKVer.h>
#include <stdio.h>
#include <string>
#include <tchar.h>

1. Flower.cpp :

Add a simple line #include "stdafx.h" at top of this file

2. Plant.ccp

Add a simple line #include "stdafx.h" at top of this file

3. Add a new File stdafx.cpp which has followng 1 line code :

#include "stdafx.h"

4. Main.cpp

#include "stdafx.h"
#include "Plant.h"
#include "Flower.h"
#include <vector>
#include <iostream>
#include <algorithm>

using namespace std;

vector<Plant *> myGarden;

void PrintVector() {
   cout << endl << "----------- My Garden Details -------------" << endl << endl;
   for (int i = 0; i < myGarden.size(); i++) {
       myGarden[i]->PrintInfo();
       cout << endl;
   }
   cout << endl << "----------- End of Garden Details -------------" << endl;
}

void AddToGarden() {
   cout << "Enter the type : (plant/flower) : ";

   string input, plantName, flowerName, flowerCost, colorOfFlowers;
   float plantCost;
   char isAnnual;
   cin >> input;
   transform(input.begin(), input.end(), input.begin(), ::tolower); //input convert to lower case

  
  
   Plant *pl = new Plant();
   Flower *fl = new Flower();

   if (input == "plant") { //type of plant
      
       //Inputting the plant details
       cout << "Enter Plant Name : ";
       cin >> plantName;
       cout << "Enter Plant Cost : ";
       cin >> plantCost;
       pl->SetPlantName(plantName);
       pl->SetPlantCost(plantCost);
       myGarden.push_back(pl);
       cout << input << " Details stored successfully" << endl;
   }

   else if (input == "flower") { // type of flower

       //Inputting the flower details
       cout << "Enter Plant Name : ";
       cin >> plantName;
       cout << "Enter Plant Cost : ";
       cin >> plantCost;
       fl->SetPlantName(plantName);
       fl->SetPlantCost(plantCost);

       //Enter the Flower color
       cout << "Enter the Color of flower : ";
       cin >> colorOfFlowers;

  fl->SetColorOfFlowers(colorOfFlowers);

       //Enter the Annual
       cout << "Is the Plant Annual ? (Y/N) : ";
       cin >> isAnnual;

       isAnnual = toupper(isAnnual); // uppercase conversion
       fl->SetPlantType(isAnnual == 'Y' ? true : false);
       myGarden.push_back(fl);
       cout << input << " Details stored successfully" << endl;
   }

   else {
       cout << "Wrong type of input given" << endl;
   }
  
}

int main(int argc, char* argv[]) {

   cout << "---------------- Welcome to my Garden --------------------" << endl;

   //Menu Driven program for adding, print the Garden Details
   while (true) {
      
       cout << endl << "Press :\n1 for Add Information for My Garden" << endl <<
       "2 for Print Garden Details" << endl << "3 for Exit" << endl << "\n\t Enter your choice : ";

       int choice;
       cin >> choice;
       switch (choice)
       {
           case 1: AddToGarden(); break;
           case 2: PrintVector(); break;
           case 3: for (size_t i = 0; i < myGarden.size(); ++i) {
                       delete myGarden.at(i);
                   }
                   cout << "Press Any Key to exit ";
                   getchar();
                   exit(0);
           default: cout << "Invalid Option Selected. Please try again"; break;
       }
   }

   return 0;
}

Note: The program is case in-sensitive, so you are free to given any case of input
