我需要我的彩票计划来计算10次运行后0,1,2,3,4或5个数字匹配的次数，然后显示它们。它还应该通过向累积奖金添加一定数量来跟踪总累积奖金，具体取决于获胜的数量。我的问题是，对于每个单独的运行，这是正确的计算，但不是所有十次运行总计。这就是我所拥有的。

答案 0 :(得分：0)
首先，由于您的代码有点混乱且没有注释，我不确定理解所有内容，您应该尝试清除它，您将更容易理解并发现错误。
关于我所看到的问题：
如果我正确理解你想要保留＆＃34; Jackpot＆＃34;超过10轮。这不会发生，因为在您正在执行的主要功能中
for(int i = 0; i <10; i++)
{
lottery pic = new lottery();
....
}
因此，您正在为每次运行创建一个新的彩票，并在每次运行时用空的替换以前的彩票。也许这会起作用：
lottery pic = new lottery();
for(int i = 0; i <10; i++)
{
....
}
