function and array trouble

[valmaral]

Hello everyone I am working on a homework assignment. I'm having trouble with the last portion of the code that asks to input a number that corresponds to an employee number then it will print out that employees name, pay rate, hours worked, and weekly pay. I'm getting an error saying that I have to define error: cannot convert 'double' to 'double*' for argument '2' to 'void printEmployeePaycheck(char*, double*, double*)'
. I tried to alter the parameters but no luck so far. Any help is appreciated and if there is anything off about my code I'd like to hear(read) it.

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;

const int NAMELEN = 65;
const int SIZE = 20;

void printMenu();
void addEmployees(char name[][NAMELEN], double rate[], double hours[], int &count);
void displayAllEmployees(char name[][NAMELEN], double rate[], double hours[], int count);
void printEmployeePaycheck(char name[], double rate[], double hours[]);

int main()
{
    int count=0, choice;
    char name[SIZE][NAMELEN];

    double rate[SIZE], hours[SIZE];

    do
    {
        printMenu();
        cin >> choice;
        cout << endl;

        while(count == 0 && choice != 1)
        {
            cout << "You must add atleast one employee to the database! " << endl;
            cin >> choice;
        }

        switch(choice)
        {
            case 1:
                addEmployees(name, rate, hours, count);
                break;
            case 2:
                displayAllEmployees(name, rate, hours, count);
            case 3:
                printEmployeePaycheck(name, rate, hours);
                break;
            case 0:
                cout << "Goodbye. " << endl << endl;
                break;
            default:
                cout << "Invalid menu choice. Please enter valid ";
                cout << "menu choice ";
                cin >> choice;
        }
    }
    while(choice!=0);
    return(0);
}

void printMenu()
{

    cout << endl;
    cout << "Welcome to the Employee Paycheck Calculator " << endl;
    cout << "=========================================== " << endl;
    cout << "1.  Add employee record(s) to the database " << endl;
    cout << "2.  Print all employee records " << endl;
    cout << "3.  Print the paycheck for one employee " << endl;
    cout << "0.  Exit " << endl;
    cout << "=========================================== " << endl;
    cout << "Enter selection:  ";
}

void addEmployees(char name[][NAMELEN], double rate[], double hours[], int &count)
{
    cout << "How many employees do you wish to add? ";
    cin >> count;

    while (count < 1 || count > 20)
    {
        cout << "That is an invalid size. ";
        cout << "You must enter a value between 1 and 20. " << endl;
        cout << "How many employees do you wish to add? ";
        cin >> count;
    }

    for (int i = 0; i < count; i++)
    {
        cout << endl;
        cout << "Enter Employee " << i << " name: ";
        cin.ignore();
        cin.getline(name[i], NAMELEN);

        cout << "Enter " << name[i] << "'s pay rate: ";
        cin >> rate[i];

        cout << "Enter " << name[i] << "'s weekly hours: ";
        cin >> hours[i];
    }
                                               
}

void displayAllEmployees(char name[][NAMELEN], double rate[], double hours[], int count)
{
    cout << endl;
    cout << "Index" << "  " << "Name" << "\t\t";
    cout << "Rate" << "\t" << "Hours" << endl;

    for (int i = 0; i < count; i++)
    {
        cout << i << "\t" << name[i] << "\t\t";
        cout << rate[i] << "\t" << hours[i] << endl;
    }
}

void printEmployeePaycheck(char name[], double rate[], double hours[])
{
    int i;
    int count = 0;
    double pay = rate[i] * hours[i];

    for (i = 0; i < count; i++)
    {
        cout << "Enter an Employee Number: ";
        cin >> i;

        while (i < 1 || i > count)
        {
            cout << "Error: this number does not correspond to an employee. ";
            cout << "Please enter a valid number. " << endl;
            cin >> i;
        }
    }

    cout << "Employee: " << name[i] << "\t\t" << "Rate: " << rate[i];

    cout << pay << endl;
}

On line 128, you are missing a '}' to close off the 1st while-loop. You really don't need 2 of the same loop to complete that task.

Your array in the getEmployeeNumber function is 2-Dimensional, but you are passing it as a 1-Dimensional array into your printEmployeePaycheck function. try changing this?

[valmaral]

I accidently added the extra loop while pasting it to the post. So how would I change the function of getEmployeeNumber to pass it as a 2d array, though what I'm trying to pass is just the employee number (empNum) to the function printEmployeePaycheck. Or is there a way to just add all of this to the "print" function?

[Parasin]

in your parameter, just pass the employee number then put that into the array in the printEmployeePaycheck function. You should pass them separately, but by not passing the array as 2-Dimensional, it could be a problem.

okay I've rewritten the code but i'm still getting an error of;

hw6.cpp:45:42: error: cannot convert 'char (*)[65]' to 'char*' for argument '1' to 'void printEmployeePaycheck(char*, double*, double*)'


don't even know if this is the correct way to write the function, but from what i see all my parameters seem to match in the right places, i don't know why i'm still getting this error.
