C ++如何從字符串數組元素增加int變量

Question

我想知道在調用特定的字符串數組元素時是否有增加int變量的方法？ 我正在做一個有趣的項目，遇到了障礙。 我項目的目標是擁有一個確定用戶喜歡哪種電子音樂類型的程序。 該程序將顯示兩個DJ，並詢問用戶他們更喜歡哪個DJ或讓他們都不選擇。 每個DJ最多將擁有三種他們主要擅長的流派，並且我為每種流派創建了int變量（所有變量都設置為0）。 一旦用戶選擇了DJ，我希望將點分配給與DJ關聯的每個體裁變量。 我不確定如何設置此規則，因為到目前為止我嘗試過的所有操作都失敗了（代碼中注釋了兩個示例嘗試）。 最終，我的計划是開發可以隨機選擇DJ的邏輯，但是我需要首先設置類型分配。 有什么辦法可以做到嗎？ 任何幫助將不勝感激。 干杯!

//cout << trance << endl;


}

您可以在用戶選擇DJ之后增加每個提示音：

if (answer == "1") {
    cout << "You have selected: " << textArray[1] << endl;
    ++trance;
    // ++ ohter genres you want to increment
}

else if (answer == "2") {
    cout << "You have selected: " << textArray[2] << endl;
    ++trance;
    // ++ ohter genres you want to increment
}
