Question
Design a C++ program that A player rolls two dice. Each die has 6 faces. These faces contain 1, 2, 3, 4, 5, and 6 spots. After the dice have come to rest, the sum of the spots on the two upward faces are calculated. If the sum is 7 or 11 on the first roll, the player wins. If the sum is 2, 3, or 12 on the first roll, the player loses. If the sum is 4, 5, 6, 8, 9 or 10 on the first roll, the sum becomes the player’s “point.” To win, you must continue rolling the dice until you “make your point.” The player loses by rolling a 7 before making the point. Try playing this game. Start off with $1000.00 and each time you win you get back twice your bet. If you lose, you lose the amount you bet. See if you can set this up so that the program asks you if you want to stop playing. At the end print out if you are a winner or a loser.
Explanation / Answer
C++ Code:
#include <iostream>
#include <iomanip>
#include <cstdlib> // needed for functions srand() and rand()
#include <ctime> // needed for function time()
using namespace std;

int wager;
srand(time(0));
sum = rollDice(diceVals);
cout << "Your bank balance is: " << "€" << bankBalance << " ";
cout << "Please enter a wager - ";
cin >> wager;
if (wager > 1000)
{
cout << "Not valid" << endl;
