我的尝试：
我将所有重置都移到了底部，希望能清除变量，但它仍然只能运行。
What I have tried:
I moved all my resets to bottom in hope that would clear variables but it still only sometimes works.
推荐答案
你还没有理解for循环并忘记了ot她的结构成员
You havent understood the for loop and forgot the other member of your struct
//looping all members
for (int i = 0; i < 5; i++)
{
playerCards[i].nVal = 2;
playerCards[i].cSuit = 0;//reset
computerCards[i].nVal = 2;
computerCards[i].cSuit = 0;//reset
}
更清晰的是课程或功能
Clearer would be classes or a function
void resetCard(Card &card)
{
card.nval = 2;
card.cSuit = 0;
}
//used like that
for (int i = 0; i < 5; i++)
{
resetCard( playerCards[i] );
resetCard( computerCards[i] );
}
您应该学习尽快使用调试器。而不是猜测你的代码在做什么，现在是时候看到你的代码执行并确保它完成你期望的。
调试器允许你跟踪执行逐行检查变量，你会看到有一点它会停止你所期望的。

You should learn to use the debugger as soon as possible. Rather than guessing what your code is doing, It is time to see your code executing and ensuring that it does what you expect.
The debugger allow you to follow the execution line by line, inspect variables and you will see that there is a point where it stop doing what you expect.
