Question

Can someone please help me with this code? I'm writing in C++. Thank you in advance.

Complete a program that represents a Magic Eight Ball (a Magic Eight Ball allows you to ask questions and receive one of several random answers).

In order to complete this, you will need a couple of new functions.

First, in order to get a line of input that can contain spaces, you cannot use cin, but instead will use getline:

string question;

cout << "What is your question? (Enter 'x' to exit)" << endl;
getline(cin, question);

Second, an alternative to using == to compare two strings is the string compare function. We'll look later at reasons to use this, but

if (question.compare("x") == 0)

//found an "x"

Now here is the program we need to complete, Instructions for what to do to complete it are in the file as comments.

#include <iostream>

#include <string>

#include <ctime>

using namespace std;

string getAnswer(string m8Ball[], int nAnswers);

int main()

{

   //define a constant that represents how many answers are in your array (at least 8)

   //declare and initialize an array of strings, representing possible answers from the magic eightball

   srand((unsigned int) time(NULL));

   //loop and ask the user to enter a question or enter "x" to stop

   //use getline to get the question

   //call getAnswer with your array and number of possible answers to get an answer

   //output the answer

}

string getAnswer(string m8Ball[], int nAnswers)

{

   int index = rand() % nAnswers;

return m8Ball[index];

}

Answer 1

HI, Please find my implementation.

Please let me know in case of any issue.

#include <iostream>
#include <string>
#include <ctime>

using namespace std;
string getAnswer(string m8Ball[], int nAnswers);
int main()
{
//define a constant that represents how many answers are in your array (at least 8)
const int NUM_OF_ANS = 8;
//declare and initialize an array of strings, representing possible answers from the magic eightball
string m8Ball[] = {"A", "B", "C", "D", "E", "F", "G", "H"};

srand((unsigned int) time(NULL));

    string question;
//loop and ask the user to enter a question or enter "x" to stop
while(true){
   //use getline to get the question
       cout << "What is your question? (Enter 'x' to exit)" << endl;
       getline(cin, question);

       if (question.compare("x") == 0)
           break;
  
   //call getAnswer with your array and number of possible answers to get an answer
   //output the answer
   cout<<"Answer: "<<getAnswer(m8Ball, NUM_OF_ANS)<<endl;
}

}

string getAnswer(string m8Ball[], int nAnswers)
{
int index = rand() % nAnswers;

return m8Ball[index];
}
