我正在製作蒙蒂廳遊戲節目。我是新來的，我只是想知道爲什麼最後打印出來的時候，爲什麼總是打印出0.我想打印出值3，因爲我認爲他們會等於 - This Part試圖讓價值觀等於

if(door1 == 3){ 
     door1 = cdoor;} 
    if(door2 == 3){ 
     door2 = cdoor;} 
    if(door3 == 3){ 
     door3 = cdoor;}

因爲cdoor總是0.它永遠不會被修改。也許你的意思是，

if (door1 == 3) { 
    cdoor = door1; 
} 
if (door2 == 3) { 
    cdoor = door2; 
} 
if (door3 == 3) { 
    cdoor = door3; 
}

哦哇感謝:)現在我覺得啞巴。 –

我有另一個問題...當我隨機化的門1，門2和門3的值我不斷重複數字，所以我把那些如果在那裏重新隨機化他們，但它沒有奏效。任何建議@Flying_Banana –

因爲你再次隨機化，並且由於新值可以是1-3之間的任何值，所以你有33％的機會獲得相同的值。相反，你應該在1-3之間隨機選擇，然後在1-2之間隨機選擇（或者1 3或2 3，這取決於第一個門的號碼是什麼），最後門將會有剩餘數字。 –
