第六章第三十二题（游戏：赢取双骰子赌博游戏的机会）(Game: chance of winning at craps)
**6.32（游戏：赢取双骰子赌博游戏的机会）修改编程练习题6.30使该程序运行10000次，然后显示赢得游戏的次数 **6.32(Game: chance of winning at craps)Revise Exercise 6.30 to run it 15,000 times and display the number of winning games.参考代码：
package chapter06
;
public class Code_32 {
public static void main(String
[] args
) {
int sumOfTwoDice
, firstDie
, secondDie
, point
, winCount
= 0;
for(int i
= 1;i
<= 1000;i
++) {
firstDie
= rollDie();
secondDie
= rollDie();
sumOfTwoDice
= firstDie
+ secondDie
;
if (sumOfTwoDice
== 2 || sumOfTwoDice
== 3 || sumOfTwoDice
== 12) {
winCount
++;
}
else if (sumOfTwoDice
== 7 || sumOfTwoDice
== 11) {
}
else {
point
= sumOfTwoDice
;
do {
firstDie
= rollDie();
secondDie
= rollDie();
sumOfTwoDice
= firstDie
+ secondDie
;
} while (sumOfTwoDice
!= 7 && sumOfTwoDice
!= point
);
if (sumOfTwoDice
== point
)
winCount
++;
}
}
System
.out
.printf("You totally won %d times", winCount
);
}
public static int rollDie() {
return (int) (Math
.random() * 6 + 1);
}
}
结果显示：
You totally won
387 times
Process finished with exit code
