I get the error "Declaration of 'PayRoll employee [3]' shadows a parameter"

Please use code tags.
My guess, by quickly scanning your code, is that you have a problem in Gross function

void Gross(PayRoll& employee)
{
PayRoll employee[NUM_EMPLOYEE]; // employee is a PayRoll structure.]; 

You redefine employee

[dasboshiet]

So how can I make it work?

[Zhuge]

Don't use the same name for your parameter as you use for a local variable. What exactly is its purpose in this case, anyway?

[ats15]

I think you don't need to declare the employee array inside your function

[dasboshiet]

But if I don't declare it, the void function won't be able to know what "employee" is

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

using namespace std;

struct PayInfo
{
    int hours;
    double payRate;
};

struct PayRoll
{
    PayRoll();
    int empNumber;
    string name;
    double grossPay;

    PayInfo pay;
};

void GrossPay()
{
    for (int i = 0; i < 3; i++)
    {
        employee[i].grossPay = employee[i].pay.hours * employee[i].pay.payRate;
    }
}

int main()
{
    PayRoll employee[3];

    for (int i = 0; i < 3; i++)
    {
        cout << "Enter the employee's number: " << endl;
        cin >> employee[i].empNumber;

        cout << "Enter the employee's name: " << endl;
        cin.ignore();
        getline(cin, employee[i].name);

        cout << "How many  hours did the employee work?" << endl;
        cin >> employee[i].pay.hours;

        cout << "What is the employee's hourly pay rate?" << endl;
        cin >> employee[i].pay.payRate;
    }

    GrossPay();

    for (int j = 0; j < 3; j++)
    {
        cout << "Here is the employee's payroll data:\n";
        cout << "name: " << employee[j].name << endl;
        cout << "Number: " << employee[j].empNumber << endl;
        cout << "hours worked: " << employee[j].pay.hours << endl;
        cout << "Hourly pay rate: " << employee[j].pay.payRate << endl;
        cout << fixed << showpoint << setprecision(2);
        cout << "Gross Pay: $" << employee[j].grossPay << endl;
    }

    return 0;
}

recently remade it.

You have tried two options; no declaration, which fails; and two declarations, which also fails. Try declaring it only once, as a formal parameter of the function while not also declaring it as a local variable.

[dasboshiet]

How do I do that? I've never done that before >< been trying to looking it up but all I can think of is " PayRoll &employee "

[dasboshiet]

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

using namespace std;

struct PayInfo
{
    int hours;
    double payRate;
};

struct PayRoll
{
    PayRoll();
    int empNumber;
    string name;
    double grossPay;

    PayInfo pay;
};

void GrossPay(PayRoll employee[])
{
    for (int i = 0; i < 3; i++)
    {
        employee[i].grossPay = employee[i].pay.hours *
                                employee[i].pay.payRate;
    }
}

int main()
{
    PayRoll employee[3];

    for (int i = 0; i < 3; i++)
    {
        cout << "Enter the employee's number: " << endl;
        cin >> employee[i].empNumber;

        cout << "Enter the employee's name: " << endl;
        cin.ignore();
        getline(cin, employee[i].name);

        cout << "How many  hours did the employee work?" << endl;
        cin >> employee[i].pay.hours;

        cout << "What is the employee's hourly pay rate?" << endl;
        cin >> employee[i].pay.payRate;
    }

    GrossPay(PayRoll employee[]);         //Problem is Here

    for (int j = 0; j < 3; j++)
    {
        cout << "Here is the employee's payroll data:\n";
        cout << "name: " << employee[j].name << endl;
        cout << "Number: " << employee[j].empNumber << endl;
        cout << "hours worked: " << employee[j].pay.hours << endl;
        cout << "Hourly pay rate: " << employee[j].pay.payRate << endl;
        cout << fixed << showpoint << setprecision(2);
        cout << "Gross Pay: $" << employee[j].grossPay << endl;
    }

    return 0;
}

Error: expected primary-expression before 'employee'

[ne555]

GrossPay(employee);
