在我的主语言中，我必须测试使用for循环制作的类，但有点卡住。我必须循环3次，并获得票务系统的用户输入。我尝试制作一个数组并存储用户输入，但到目前为止我没有尝试过。我试图用我的循环调用SetWorkTicket。
#include<iostream>
#include<iomanip>
#include<stdexcept>
#include<sstream>
using namespace std;
// start of the WorkTicket class
class WorkTicket{
public:

WorkTicket() : myTicketNumber(0), myClientId(""), myDay (1), myMonth (1), myYear(2000), myDescription ("") { }
WorkTicket(int ticketNumber, string clientId, int month, int day, int year, string description);
// mutator method that sets all attributes of the object to the parameters as long as valid. If no problems are being detected set TRUE if not then FALSE.....
bool SetWorkTicket(int ticketNumber, string clientId, int month, int day, int year, string description);
// accessor method that will show all the attributes of the ticket in the console menu
void ShowWorkTicket() const;
// here are the sets and gets for the attributes

假设您的其余代码正常工作，并且您只在主要方面遇到问题：
在您的main代码中，其他人曾评论过一些问题：
1）您声明了WorkTicket tickets[NUMBER_OF_TICKETS];，但没有在任何地方使用它。
2）变量tickets是一个数组，因此在for循环tickets[i]中的类型为WorkTicket。
3）SetDay是WorkTicket的成员函数，并以int作为参数。
鉴于这些，进行了以下更改：
for (int i = 0; i <NUMBER_OF_TICKETS; i++)
{
cout << "\WorkTicket [" << i << "]: " << endl;
cout << "Enter the ticket number: " << endl;
cout << "Enter the client ID: " << endl;
getline(cin, clientId);
cout<<"Enter a day number:";
int day;
cin>>day;
tickets[i].SetDay(day); //day is int and tickets[i] is of WorkTicket
}
希望这有助于更好地了解main部分。

收集输入，然后构造一个工作票。将票推入向量。在尚未编写的代码中，可以测试新创建的WorkTickets的正确性。
确保在文件顶部包含vector。
int main()
{
const int NUMBER_OF_TICKETS = 3;
int ticketNumber;
string clientId;
int day;
int month;
int year;
string description;
std::vector<WorkTicket> tickets;
for (int i = 0; i <NUMBER_OF_TICKETS; i++)
{
cout << "WorkTicket [" << i << "]: " << endl;
cout << "Enter the ticket number: " << endl;
cin>> ticketNumber;
cout << "Enter the client ID: " << endl;
cin >> clientId;
cout << "Enter a day number: " << endl;
cin >> day;
cout << "Enter a month number: " << endl;
cin>> month;
cout << "Enter a year number: " << endl;
cin>> year;
cout << "Enter a description : " << endl;
cin >> description;
try {
tickets.push_back({ticketNumber, clientId, month, day, year, description});
}
catch(std::exception e)
{
std::cout << e.what() << std::endl;
}
}
}
