C++ 在if/else语句中调用数组的成员

我试图写一个if/else语句，对数组的所有成员说“如果随机选择的问题是数组中的第一个，那么就这样做…”等等。但是，它默认选择每个问题作为数组的第一个成员并执行该操作。我怎样才能把它分开呢

if (choice == 1)
        {
            enum fields{ QUESTS, ANS_1, ANS_2, ANS_3, ANS_4, NUM_FIELDS };
            string QUEST[NUM_QUEST][NUM_FIELDS] =
            {
                { "What course is this?\n", "A)C++\n", "B)DID\n", "C)Intro to Game\n", "D)Yoga" },
                { "Who am I?\n", "A)Bill\n", "B)Nye\n", "C) 24601\n", "D)No one\n" },
                { "Are you actually reading this?\n", "A) Yes\n", "B)No\n", "C)Maybe\n", "D)Who wants to know?\n" },
                { "Will this program work?\n", "A)Of course it will!\n", "B)It might\n", "C)Are you kidding me?\n", "D)Gods only know." },
                { "Where would I rather be?\n", "A)Home\n", "B)Europe\n", "C)Anywhere but here\n", "D)All of the above\n" }
            };
            srand(static_cast<unsigned int>(time(0)));
            int randomQuest = (rand() % NUM_QUEST);
            string question = QUEST[randomQuest][QUESTS];
            cout << question;
            string printAns1 = QUEST[randomQuest][ANS_1];
            string printAns2 = QUEST[randomQuest][ANS_2];
            string printAns3 = QUEST[randomQuest][ANS_3];
            string printAns4 = QUEST[randomQuest][ANS_4];
            cout << printAns1;
            cout << printAns2;
            cout << printAns3;
            cout << printAns4;
            cout << "\nAnswer:";
            string answer;
            cin >> answer;
