-1
我遇到了與實際程序有關的問題。在用戶選擇1或2與電腦或人對戰後，顯示的下一行是「這是一個平局」，它會跳過整個遊戲。我不確定爲什麼，因爲我將turnNum設置爲0，並在while循環的開始處增加1，並且如果turnNum等於10，它應該只是一個抽獎遊戲。我的代碼是否不正確？函數不起作用，當我叫它

謝謝！我包括cstdlib。我不知道rand是在該庫中定義的。但是現在我遇到了一個與實際計劃相關的問題。在用戶選擇1或2與電腦或人對戰後，顯示的下一行是「這是一個平局」，它會跳過整個遊戲。我不知道爲什麼，因爲我將turnNum設置爲0，並在代碼的開頭增加1。我的代碼不正確？ – user2085224
