それで、私は今しばらくこのプログラムを作っています。私はインターネット全体を見てきましたが、私が見つけた解決策はどれもうまくいきませんでした。arr[i].question と arr[i].answer に入力を入れるたびに、質問に答えなくても、質問が間違っていると表示されます。cin.ignore()、cin.clear()、および cin.sync() を使用してみました。間違った場所で使用していた可能性がありますが、よくわかりません。混乱するかもしれないので、コードを見てください。
入力形式はこちら。
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();
}
そして、これがあなたにクイズを出すためのアウトプットフォーマットです。
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++;
}
質問を入力しても、コンソールに質問が出力されないか、回答を入力できません。それは間違っていると言っているだけです。少し助けてください？

間違っている前に、最初の質問が表示され、答える機会が与えられます。私ができる前に、それはただ間違っていると言います。次に、最初の文字が欠落している回答を表示します。ほらね。
