我有2件事不能使用此代码。第一件事就是在我的第二个do-while循环中，当我输入＆＃39; g＆＃39;或者＆＃39; G＆＃39;然后我放入坐标并选择它是左还是右连续循环 我不能正常工作的第二件事是，当我拍摄激光时，挡板应转动它并使其向不同的方向移动。这可以工作，但它不能将激光器转动到挡板定位后的盒子。我对此非常感兴趣，任何帮助都会很棒，任何你看到我应该修复的东西都会非常感激。

我没有完整的解决方案，但有几件事情。
您应该简化while循环测试。 这个怎么样（伪代码）：
bool done = false;
while (!done) {
// Process action loop
cin >> action;
action = toupper(action); // Make everything upper case
processTheAction(action);
done = areWeDoneYet(action);
}
将复杂的“我们已经完成”任务和其他事情分解为功能。 （分而治之）
bool areWeDoneYet(action) {
switch (action) {
case A:
case B:
... (cases where we are not done)
return false;
case E:
case F:
... (cases where we are done)
return true;
}
}
简化“事件循环”。让它称为复杂的功能 “ProcessAction”通过这种方式，您可以判断在遇到问题时是否正忙于处理，或者您是否遇到事件循环问题。
void processTheAction( action ) {
switch (action) {
case A:
case a: // Optional method if you don't do topper on Action
// Code for action 'A' goes here
// If a *lot* of code make a function like "ProcessActionA()"
break;
case B:
case b: // not needed if you do topper
// Code for action 'B' goes here
break;
default:
printf("I'm hosed cause I forgot to manage action [%c]\n",
action);
}
}
不知道这是否有帮助，但它可以帮助您解决问题。
