C++ 设置私有数组的值

Question

我正在用 C++ 创建 Yahtzee。骰子掷出一个数字，根据掷出的数字，通过从 randNum 中减去 1 来创建一个位置（因为数组是从零开始的）。然后使用该位置，我想增加数组中的适当元素以表示我已经滚动了该特定数字。例如：掷骰子 1,1,1,5,6,4。我的数组应该显示：3,0,0,1,1,1。使用我当前的代码，元素不会增加。任何帮助表示赞赏。

标题：

class dice {
public:
    dice();
    void rollDice();
    int getRoll(int diceNumber);

    //This is the array that tells us how many of one number we have
    //ex) element 4 belongs to the #5 so if there is a 3 stored in element 4 that means we rolled 3 5's
    int arrayOfEachNumberRolled[5]{0,0,0,0,0};

    ~dice();
}

来源：

void dice::rollDice(){
    //roll a random number and store it in the appropriate location
    int randNum;
    for(int i = 0; i < 6; i++){

        //Get the new random number between 1 & 6
        randNum = rand() % 6 + 1;
        //set the appropriate dice
        if(i == 0){//dice1
            dice1->set(randNum);
            arrayOfEachNumberRolled[randNum - 1]+=1;
        }
        else if(i == 1){//dice 2
            dice2->set(randNum);
            arrayOfEachNumberRolled[randNum - 1]++;
        }
        else if(i == 2){//dice 3
            dice3->set(randNum);
            arrayOfEachNumberRolled[randNum - 1]++;
        }
        else if(i == 3){//dice 4
            dice4->set(randNum);
            arrayOfEachNumberRolled[randNum - 1]++;
        }
        else if(i == 4){//dice 5
            dice5->set(randNum);
            arrayOfEachNumberRolled[randNum - 1]++;
        }
        else if (i == 5){//dice 6
            dice6->set(randNum);
            arrayOfEachNumberRolled[randNum - 1]++;
        }
    }
}

Answer 1

您需要一个包含 6 个元素的数组，而不是 5 个。更改

int arrayOfEachNumberRolled[5]{0,0,0,0,0};

到

int arrayOfEachNumberRolled[6]{0,0,0,0,0,0};
