Array of Structures - Functions not pulling through data - c++

Question

I am studying BscCS so I am familiar with programming concepts, however I always seem to get stuck on structs and arrays of structs.
I am required to convert parallel arrays into an array of structs. I have done this, but for some reason the information is not getting sent to the functions properly and the program keeps crashing.
Could you help identify where I am going wrong of if there is something I am missing? I don't need exact code for answers, just some guidance. Here is the code:
#define SIZE 3
struct Employee {
string firstName[SIZE];
string lastName[SIZE];
int id[SIZE];
int hoursWorked[SIZE];
int payRate[SIZE];
int stat[SIZE];
};
//Functions
int menu();
void printReport(Employee & employees);
void search(Employee & employees);
void calculatePay(Employee & employees);
void orderByLastName(Employee & employees);
void orderByid(Employee & employees);
void printActive(Employee & employees);
void printInactive(Employee & employees);
//Display Main Menu
int menu()
{
int choice;
cout << "1. Print out Employee Report. " << endl;
cout << "2. Search Employee Records. " << endl;
cout << "3. Display the Report in Sorted order on Last Name or ID. << endl;
cout << "4. Calculate Pay. " << endl;
cout << "5. Display Active Employees." << endl;
cout << "6. Display Inactive Employees." << endl;
cout << "7. Quit" << endl;
cout << "Enter your choice. ";
cin >> choice;
return choice;
}
//Display the employee data in a formatted order
void printReport(Employee & employees)
{
cout << setw(10) << "First Name" <<
setw(10) << "Last Name" <<

I ran your program, and I received more than 20 errors before the compiler involuntarily stopped trying to compile any longer. All of them are connected to the lines of code using cout, cin, string, and setw. You need to use these keywords with the std namespace to fix this, and you need to include the iostream header file (#include <iostream>). Either you can write std:: in front of all of these keywords (i.e. std::cout) or you can declare the namespace in the preprocessor (using namespace std;). Also, for std::setw, you need to include the iomanip header file (#include <iomanip>). After that, you're missing a quotation in the menu function and a bracket at the end of the main function. (There's also a couple of problems with initializing the size of the struct members in the declaration, but I'll leave that up to you.) Hope this helped!
