Question

in C++

This assignment is to use your knowledge of Chap 1-5 to write a simulation program to estimate the winning chance of the Craps game. Craps is a popular dice game played in casinos. Here is how to play: Roll two dice. Each die has 6 faces representing values 1,2,3,4,5,and 6, respectively. Check the sum of 2 dice. If the sum is 2, 3, or 12 (called craps), you lose; if the sum is 7 or 11 (called natural), you win; if the sum is another value (i.e., 4,5,6,8,9,or10) a point is established. Continue until you roll either a 7 (you lose) or the same point value (you win). Here are few cases: 1. You rolled 5 + 6 = 11 You win 2. You rolled 1 + 2 = 3 You lose 3. You rolled 4 + 4 = 8 Point is 8, then you rolled 5 + 6 = 11 (continue rolling), then rolled 6 + 2 = 8 (You win) 4. You rolled 3 + 2 = 5 Point is 5, then you rolled 2 + 5 = 7 (You lose) Let the game be played for 1000 times to estimate the winning chance. Report the chance. Note: You’ll need to use random number function, rand(). (See page 129 of your textbook for proper header files and using system time for random seed) Besides, when you roll a die, use formula, rand()%6+1, to get the random face value of a die. A day before the due date, the number of plays will be released on Blackboard, which your submission of the assignment needs to follow.

Answer 1

#include <iostream>
#include <cstdlib>
#include<ctime>
using namespace std ;

int main(void)
{


    srand(time(0));



    int  point = rand() % 6 + 1;
    point = point + rand() % 6 + 1;
    double loss = 0   ;
    double  win = 0   ;

    int count = 0 ;// one time game has been played

   while(  count <  1000 ) {



       if (point == 2 || point == 3 || point == 12) {
           loss++;
           count++;
           point = 0;
           continue ;
       }

    else    if (point == 7 || point == 11) {
           win++;
           count++;
           point = 0 ;
       }
     else   if (point == 4 || point == 5 || point == 6 || point == 8 || point == 9 || point == 10) {

           point = (point + rand() % 6 + 1) % 12 + 1;
           continue;
       }


       point = rand() % 6 + 1;
     point =   point + rand() % 6 + 1;
   }







//calculate probability
    double  win_chance   = win /1000;

cout<< " The probability to win is " << win_chance<< endl ;


    return 0;
}
