使用指针从结构中显示字符串？

Question

我使用指针显示用户输入的数据，但是当我尝试显示用户输入的数据时，字符串不会显示在案例3上。相反，空白会显示。我将字符串更改为字符并且有效。只是想知道为什么字符会显示，但字符串不会显示？

#include <iostream>
#include <iomanip>
#include <string>

using namespace std;

struct employeeRec
{
string employee_id;
string last_name;
string first_name;
float hrs_worked;
float pay_rate;
float tax_rate;
};

int main()
{
bool again = true;
int recorded = 0, remaining = 20;

while (again)
{
    const int max = 20;
    int written, option;
    employeeRec *p, records[max];

    p = &records[0];

    cout << "\n1 - Enter new employee(s)\n"
         << "2 - Find one employee record\n"
         << "3 - Display all employee records\n"
         << "4 - Quit\n\n";

    cout << "Enter an option: ";
    cin >> option;

    switch (option)
    {
        case 1:
        {
            cout << "\nHow many records do you wish to enter? (Max total of 20 records): ";
            cin >> written;

            cin.ignore();

            if (written < 0)
            {
                written = written * -1;
            }

            for (int n = 0; n < written; n++)
            {
                cout << "\nRecord #" << n << "\n";
                cout << "1 of 6 - Enter Employee ID: ";
                getline(cin, p -> employee_id);

                cout << "\n2 of 6 - Enter Employee Last Name: ";
                getline(cin, p -> last_name);

                cout << "\n3 of 6 - Enter Employee First Name: ";

                cout << "\n5 of 6 - Enter Pay Rate: ";
                cin >> p -> pay_rate;

                p++;
            }

            recorded = recorded + written;
            remaining = remaining - recorded;

            break;
        }

        case 2:

           cout << "\nFind an employee option";
           break;
        }

                p++;
            }
            break;
        }

        case 4:
        {
            cout << "\nQuitting...";
            again = false;
            break;
        }

        default:
