如果用户试图在C++中输入意外类型的信息，如何处理异常

我正在编写一个程序，如果用户试图输入，我应该处理异常意外类型的信息(例如，如果输入的是数字，而所需的是字符串，则要求他重新输入有效的输入(。

问题是，我的代码适用于所有(int(类型(比如，如果用户在(int(文件中输入字符串，则会给出重新输入的消息(。但是，它不适用于(字符串(类型。

这是我的代码：

void TA::AddnewTA(TA TA_Arr[], TA New_TA_Arr[], int &TA_Arr_Num, int &New_TA_Arr_Count)
{
// Prompt the user to enter the TA ID
while (true) 
{
cout << "Please Enter TA ID:n";
cin >> New_TA_Arr[New_TA_Arr_Count].Student_ID;
while (1)
{
// Checking if the ID entered is of an unexpected type (handle the ID exception)
// Using (cin.ignore) to ignore data entered to the end of line along with clean
if (cin.fail())
{
cin.clear();
cin.ignore(numeric_limits<streamsize>::max(), 'n');
cout << "Unexpected Type is entered, Please Enter once more a valid ID input: " << endl;
cin >> New_TA_Arr[New_TA_Arr_Count].Student_ID;
}
// If the type is correct, break & go check if the ID entered is duplicated or not
if (!cin.fail())
break;
}
// Use Duplicate_Student_ID Function to check on the ID existence
// If the ID is already there, then request from the user to enter another ID
if (Duplicate_Student_ID(TA_Arr, New_TA_Arr, TA_Arr_Num, New_TA_Arr_Count, New_TA_Arr[New_TA_Arr_Count].Student_ID) == true) 
{
cout << "Unfortunately, Your Entered ID is Already Exist. Please Enter Another Valid IDn"; 
continue;
}
// If it is a New ID, then complete to the First Name Data!!
else {break;}
}
// Prompt the user to enter the TA First Name
cout << "Please Enter TA First Name: ";
cin >> New_TA_Arr[New_TA_Arr_Count].First_N;
while (1)
{
// Checking if the First Name entered is of an unexpected type (handle the First Name exception)
// Using (cin.ignore) to ignore data entered to the end of line along with clean
if (cin.fail())
{
cin.clear();
cin.ignore(numeric_limits<streamsize>::max(), 'n');
cout << "Unexpected Type is entered, Please Enter once more a valid First Name input:" << endl;
cin >> New_TA_Arr[New_TA_Arr_Count].First_N;
}
// If the type is correct, break & go to Last Name Entry Data
if (!cin.fail())
break;
}
// Prompt the user to enter the TA Last Name
cout << "Please Enter TA Last Name: ";
cin >> New_TA_Arr[New_TA_Arr_Count].Last_N;
while (1)
{
// Checking if the Last Name entered is of an unexpected type (handle the Last Name exception)
// Using (cin.ignore) to ignore data entered to the end of line along with clean
if (cin.fail())
{
cin.clear();
cin.ignore(numeric_limits<streamsize>::max(), 'n');
cout << "Unexpected Type is entered, Please Enter once more a valid Last Name input:" << endl;
cin >> New_TA_Arr[New_TA_Arr_Count].Last_N;
}
// If the type is correct, break & go to Start Hire year Entry Data
if (!cin.fail())
break;
}
// Prompt the user to enter the TA Start Year of Hire
cout << "Please Enter TA Start Hire year: ";
cin >> New_TA_Arr[New_TA_Arr_Count].Start_Hire_Year;
while (1)
{
// Checking if the Start Hire year entered is of an unexpected type (handle the Start Hire year exception)
// Using (cin.ignore) to ignore data entered to the end of line along with clean
if (cin.fail())
{
cin.clear();
cin.ignore(numeric_limits<streamsize>::max(), 'n');
cout << "Unexpected Type is entered, Please Enter once more a valid Start Hire year input:" << endl;
cin >> New_TA_Arr[New_TA_Arr_Count].Start_Hire_Year;
}
// If the type is correct, break & go to End Hire year Entry Data
if (!cin.fail())
break;
}
// Prompt the user to enter the TA Class (Grad/Alum)
cout << "Please Enter TA Class (Grad/Alum): ";
cin >> New_TA_Arr[New_TA_Arr_Count].Class;
while (1)
{
// Checking if the TA Class entered is of an unexpected type (handle the Class exception)
// Using (cin.ignore) to ignore data entered to the end of line along with clean
if (cin.fail())
{
cin.clear();
cin.ignore(numeric_limits<streamsize>::max(), 'n');
cout << "Unexpected Type is entered, Please Enter once more a valid Class input:" << endl;
cin >> New_TA_Arr[New_TA_Arr_Count].Class;
}
// If the type is correct, break & go to TA Working Hours Entry Data
if (!cin.fail())
break;
}
// Prompt the user to enter the TA Working Hours
cout << "Please Enter TA Working Hours: ";
cin >> New_TA_Arr[New_TA_Arr_Count].Working_H_Num;
while (1)
{
// Checking if the TA Working Hours entered is of an unexpected type (handle the Working Hours exception)
// Using (cin.ignore) to ignore data entered to the end of line along with clean
if (cin.fail())
{
cin.clear();
cin.ignore(numeric_limits<streamsize>::max(), 'n');
cout << "Unexpected Type is entered, Please Enter once more a valid Working Hours input:" << endl;
cin >> New_TA_Arr[New_TA_Arr_Count].Working_H_Num;
}
// If the type is correct, break & call the function to print all attributes to the main function in Test Driver
if (!cin.fail())
break;
}
// Count Up the New TA Array Counter to add the New Added TA Info to the TAs.txt
New_TA_Arr_Count++;
} 

所以，ID&Working_H_Num正在工作，但名字、姓氏和类不起作用！！请帮忙！！
