Question

12. Coin Toss Simulator Write a class named Coin. The Coin class should have the following member variable: • A string named sideUp. The sideUp member variable will hold either "heads" or "tails" indicating the side of the coin that is facing up. The Coin class should have the following member functions: • A default constructor that randomly determines the side of the coin that is facing up (“heads" or "tails") and initializes the sideUp member variable accordingly. • A void member function named toss that simulates the tossing of the coin. When the toss member function is called, it randomly determines the side of the coin that is facing up ("heads" or "tails") and sets the sideUp member variable accordingly. • A member function named getSideUp that returns the value of the sideUp member variable. Write a program that demonstrates the Coin class. The program should create an instance of the class and display the side that is initially facing up. Then, use a loop to toss the coin 20 times. Each time the coin is tossed, display the side that is facing up. The program should keep count of the number of times heads is facing up and the number of times tails is facing up, and display those values after the loop finishes.

implement coinclass and driver program within one source file, i.e. do not separate class specifications with implementation

Its a c++ problem

Answer 1

Note: I can only answer the first question as I need to follow the HOMEWORKLIB RULES. The answer to the first question is given below.

Program:

#include <iostream>

#include <ctime>

#include <cstdlib>

using namespace std;

class Coin

{

    string sideUp; //  member variable sideUp

public:

    // constructor that randomly determines the side of the coin

    // that is facing up

    Coin()

    {

        if (rand() % 2 == 0)

        {

            sideUp = "heads";

        }

        else

        {

            sideUp = "tails";

        }

    }

    // void member function that simulates the tossing of the coin

    // it randomly determines the side of the coin that is facing up

    void toss()

    {

        if (rand() % 2 == 0)

        {

            sideUp = "heads";

        }

        else

        {

            sideUp = "tails";

        }

    }

    // it returns the value of the sideUp member variable

    string getSideUp()

    {

        return sideUp;

    }

};

// Driver program

int main()

{

    srand(time(0));

    Coin coinObject;

    int numberOfHeads = 0, numberOfTails = 0;

    // display the side that is initially facing up

    cout << "The side that is initially facing up: " << coinObject.getSideUp() << endl;

    // loop to toss the coin 20 times

    for (int i = 1; i <= 20; i++)

    {

        coinObject.toss();

        // each time the coin is tossed, display the side that is facing up

        cout << "The side that is facing up after " << i << " toss: " << coinObject.getSideUp() << endl;

        if (coinObject.getSideUp() == "tails")

        {

            numberOfTails++;

        }

        else

        {

            numberOfHeads++;

        }

    }

    // display the number of times heads is facing up

    cout << "Number of times heads is facing up: " << numberOfHeads << endl;

    // display the number of times tails is facing up

    cout << "Number of times tails is facing up: " << numberOfTails << endl;

    return 0;

}
