Question

C++ Program:

Given the following C++ code, complete it so that it keeps track of the Detroit Tigers record and winning percentage. The prompt asks the user for one of four options. Here are the options and what they do:

● “w” for win – this adds one to the number of wins and shows the record in a wins-losses format (for example, 4-3).

● “l” for loss – this adds one to the number of losses and shows the record in a wins-losses format.

● “p” for percentage – this calculates and shows the winning percentage. The formula is (wins / (wins + losses)).

● “x” to exit – this is the sentinel value.

This id the code given

// Your header comments here

#include <fstream>

#include <iomanip>

#include <iostream>

#include <stdlib.h>

#include <string>

using namespace std;

int main()

{

// Declare and initialize variables

// Your code here

char Option;

// Show application header

// Your code here

// Prompt for and read first option

cout << endl;

cout << "Enter an option "

   << "(w-win, l-loss, p-percentage, x-exit): ";

cin >> Option;

// Loop to process options

while (Option != 'x')

{

// Your code here

}

// Show closing message

// Pause system before application closes

system("pause");

}

Answer 1

#include <fstream>
#include <iomanip>
#include <iostream>
#include <stdlib.h>
#include <string>

using namespace std;

int main()
{
// Declare and initialize variables
int wins, losses;
char Option;
// Show application header
// Your code here
// Prompt for and read first option
cout << endl;
cout << "Enter an option "
<< "(w-win, l-loss, p-percentage, x-exit): ";
cin >> Option;
// Loop to process options
wins = 0;
losses = 0;
while (Option != 'x')
{
if(Option == 'w')
{
wins++;
cout<<endl<<"Win-Loss: "<<wins<<"-"<<losses<<endl;
}
if(Option == 'l')
{
losses++;
cout<<endl<<"Win-Loss: "<<wins<<"-"<<losses<<endl;
}
if(Option == 'p')
{
cout<<endl<<"Percentage: "<<(float) wins / (wins+losses) * 100<<endl;
}
  
cout << endl;
cout << "Enter an option "
<< "(w-win, l-loss, p-percentage, x-exit): ";
cin >> Option;
  
}
cout<<endl<<"Thanks!";
// Show closing message
// Your code here
// Pause system before application closes
system("pause");
}

OUTPUT:
