c++ - 为什么我的部分代码被跳过而不让我输入？

Question

当我为第一个问题输入大量信息时，为什么我的代码会跳过最后一个问题？我做错了什么？

const int SIZEC =31;
char phrase[SIZEC];
cout << " Provide a phrase, up to 30 characters with spaces. > " << endl;
cin.getline(phrase, SIZEC);
cin.ignore(numeric_limits<streamsize>::max(), '\n');
cout << " The phrase is: " << phrase << endl;
cout << endl;


cout << " Using sring Class Obects " << endl;
cout << "--------------------------" << endl;
cout << endl;

string leter;
cout << " Provide a single character > " << endl;
cin >> leter;
cout << " The single character is: " << leter << endl;
cout << endl;

如果需要之前的代码，请告诉我，我会添加它。

使用std::string::resize作为解决方法。

string phrase;
getline(cin, phrase);
phrase.resize(30);    // phrase will be reduced to 30 chars

string letter;    // better to use char letter
cin >> letter;
letter.resize(1);
