c++ - 如何使用多次调用 getline() 函数

Question

#include <iostream>
using namespace std;

int main()
{
    string studentName;
    char grade;
    string teacherComment;

    cout << "Enter student name: ";
    getline(cin, studentName);
    cout << "Enter grade: ";
    cin >> grade;
    cout << studentName << " has received a grade of " <<grade<< endl;
    cout << "Enter comments: ";
    getline(cin, teacherComment);
}

我知道这个getline()函数是用来从用户那里获取一串文本输入的，但是为什么第二次就不行了呢？我的程序运行良好，只是它不识别最后一行代码。
