Question

This lab explores the difference between the string type and the enum type. The attached header file defines an enumeration type, Color, representing different colors.

• Create vector of Color variables (see Lab 13 to review vectors).
• Use a loop to ask the user to enter the names of colors.   
  • For each color entered, add the corresponding Color enumeration value to the vector.
  • Ignore any invalid color that is entered (that is, a color that doesn't exist in the enumeration).
  • Exit the loop when end is entered.
• After exiting the loop, iterate through the vector printing out each of the values in the vector.

Sample output (user input is in bold):

What color do you want to add? 
red

What color do you want to add? 
yellow

What color do you want to add? 
superdupergreen

What color do you want to add? 
orange
What color do you want to add? 
blue
What color do you want to add? 
blue
What color do you want to add? 
green
What color do you want to add? 
indigo
What color do you want to add? 
violet
What color do you want to add?

//This is the attached header file called balloon.h

#ifndef BALLOON_H
#define BALLOON_H
enum Color {red, orange, yellow, green, blue, indigo, violet};
#endif

Answer 1

Please find the code below:::

balloon.h

#ifndef BALLOON_H
#define BALLOON_H
enum Color {red, orange, yellow, green, blue, indigo, violet};
#endif

main.cpp

#include <iostream>
#include <string>
#include <vector>
#include "balloon.h"
using namespace std;

int main( )
{
   vector<Color> colors;
   Color color;
   string input;
   while(true){
       cout<<"What color do you want to add? ";
       cin>>input;
       if(input=="end"){
           break;
       }else if(input=="red"){
           color = red;
           colors.push_back(color);
       }else if(input=="orange"){
           color = orange;
           colors.push_back(color);
       }else if(input=="yellow"){
           color = yellow;
           colors.push_back(color);
       }else if(input=="green"){
           color = green;
           colors.push_back(color);
       }else if(input=="blue"){
           color = blue;
           colors.push_back(color);
       }else if(input=="indigo"){
           color = indigo;
           colors.push_back(color);
       }else if(input=="violet"){
           color = violet;
           colors.push_back(color);
       }
   }
   for(int i=0;i<colors.size();i++){
       cout<<colors[i]<<endl;
   }
   return 0;
}

output:
