這是一個運行蒙蒂廳遊戲的代碼，用戶從三扇門中選擇一扇門。一扇門有獎品，另外兩個是假的。用戶選擇門1，門2或門3，並選擇是否在程序打開其中一個錯誤門時切換門。Monty Hall遊戲：如何打印電腦打開的門

如何讓程序打開一扇門，這個門必須是一個後面沒有獎品的門，而不是由用戶和打印其決定。

這裏是打印什麼：

... 
Choose door (1,2,3): 
Enter 1 for stay; 2 for switch: 
You win/lose. 
...

這是我想打印：

... 
Choose door (1,2,3): 
Door X has been opened to reveal a false door. 
Enter 1 for stay; 2 for switch: 
You win/lose. 
...

我感謝你的幫助。謝謝你，歡呼！

Monty ** Hall **，不是嗎？ –

是的，我拼錯了遊戲的名字。道歉。 – user1742525

只要選擇一個隨機的門，並且如果門是選定的門和/或獎品門，則增加或減少門號碼。

以遞增到下一門1,2,3,1,2,3，...順序：

door = door%3 + 1;

要減小：

door = (door + 1)%3 + 1;

...或只是增量兩次。
