Question

在这种情况下，我该如何解决这个问题？我看过其他帖子有同样的问题，我似乎无法将其应用于此。我之前已经解决了这个问题，但由于某些原因我不记得我是怎么做到的。

Answer 1

好吧，我在评论中得到了答案。我混淆了这一行的顺序：dice_total = specialsum;

Answer 2

int specialsum = 0;

将整数变量初始化为零或已知值。像这样定义你的变量，“int specialsum;” ，它迷路了。同时尝试specialsum= dice_total;而不是dice_total=specialsum;，因为“dice_total”始终等于零。希望这有帮助。
