我已经制作了这个程序一段时间了。我在互联网上查找过，但我找到的任何解决方案都不起作用。每次我将我的输入放入arr[i].question和arr[i].answer中时，它都会说我的问题是错误的，而我并没有回答这个问题。我尝试使用cin.ignore()、cin.clear()和cin.sync()，但可能我在错误的地方使用了它们，所以我不确定。也许我表达得有点混乱，请看一下代码。
以下是输入格式。
每当我输入问题时，它不会在控制台输出问题或让我输入答案。它只会说错了。 请帮忙解决一下？
编辑：以下是整个代码：
当我运行它时，会出现这样的情况。
那么它就直接跳到：
在回答错误之前，应该先显示第一个问题，并让我有机会回答。但实际情况是，在我来得及回答之前就显示了“错误”，然后只显示了第一个字符缺失的答案。就是这样。
以下是输入格式。
cin >> count;
cin.ignore();
for(int i =0; i < count; i++){
cout << "Enter the question.\n" << endl;
//enter the question
getline(cin, arr[i].question);
cin.ignore();
cout << "Enter the answer.\n" << endl;
//enter the answer
getline (cin, arr[i].answer);
cin.ignore();
}
以下是输出格式，用于测试。
for(int j =0; j < count; j++){
cout << "\n" << arr[j].question << endl;
getline(cin, userguess);
if(arr[j].answer.compare(userguess) !=0){
cout << "Wrong. Keep trying!\n";
incorrect++;
total++;
}
if(arr[j].answer.compare(userguess) ==0){
cout << "Nice job. Keep it up!\n";
correct++;
total++;
}

Flash Card Runner
This program was made by Jacob Malcy
Beta 3.8
IN ORDER FOR YOU TO HAVE MULTIPLE WORD FLASH CARDS,
SKIP NUMBER ONE FLASH CARD QUESTION AND ANSWER!
This is a bug is currently being worked on.
if you happen to have problems, conntact Jacob.
Would you like to create or test? Enter 0 for create and 1 for test.
如果我输入了零：
How many flashcards do you want?
假设我输入两个2
Enter the question.
Hi ho
Enter the answer.
Merry oh
enter the question.
fi fa
enter the answer.

那么它就直接跳到：
Wrong. Keep trying!
