一个扔骰子问题，先扔两次，和为7或11，玩家赢，为2,3或12为玩家输，若为其他数，则这个数为“点数”，继续扔，一直扔到和为点数，玩家赢。但若和为7时，玩家输。
问题是if (sum != 11||sum != 12||sum !=7||sum != 2||sum !=3)没有起作用，不管第一次扔赢还是输，总会扔第二次。

Answer 1

if (sum != 11||sum != 12||sum !=7||sum != 2||sum !=3)

=====================>>>>>>>>>>>>

if (sum != 11 && sum != 12 && sum !=7 && sum != 2 && sum !=3)
