get function returns invalid value

Shaun Peretz

I'm working on a code for a school project which I can't use strings.
I'm having problems getting the value for hourlyPay.
The program's output: 5 Christine Kim 4.94066e-324
Although, the file contains the following:
5 Christine Kim 30.00

#include <iostream>
#include <iomanip>
#include <fstream>
#include <cstring>

using namespace std;

//Class decleration
class Employee 
{
  private:
    int id;            //Employee ID.
    char name[21];        //Employee name.
    double hourlyPay;   //Pay per hour.

  public:
    Employee(int initId=0, char [] =0, double initHourlyPay=0.0);  //Constructor.

    bool set(int newId, char [], double newHourlyPay);
    int getId() { return id; }
    const char * getName() { return name;}
    double getHourlyPay() { return hourlyPay;}


};

Employee::Employee( int initId, char initName[], double initHourlyPay)
{
  bool status = set( initId, initName, initHourlyPay);

  if ( !status )
  {
    id = 0;
    strcpy(name, "");
    hourlyPay = 0.0;
  }
}

bool Employee::set( int newId, char newName[], double newHourlyPay)
{
  bool status = false;

  if ( newId > 0)
  {
    status = true;
    id = newId;
    strcpy(name, newName);
    hourlyPay = newHourlyPay;
  }
  return status;
}

const int MAX_SIZE = 100;


int main()
{

    int id;             //Employee ID.
    char newName[21];

    double hourlyPay;   //Pay per hour.


    Employee list[15];  //Array to store


    ifstream masterFile;        //Opens master file.

    masterFile.open("master10.txt");

    int count = 0;
    if (masterFile)
    {
        for (count; count < 2; count++)
        {
            masterFile >> id;
            masterFile.ignore();
            masterFile.getline(newName, 21);
            masterFile >> hourlyPay;
            list[count].set(id, newName, hourlyPay);
        }
    }

    masterFile.close(); //Close master file.

    cout << list[0].getId() << "   " << list[0].getName() << "  " << list[0].getHourlyPay();
}

The original file contains more lines, but I narrowed it down in order to figure out my error.
What am I doing wrong?

I have figured it out.

#include <iostream>
#include <iomanip>
#include <fstream>
#include <cstring>

using namespace std;

//Class decleration
class Employee 
{
  private:
    int id;            //Employee ID.
    char name[21];        //Employee name.
    double hourlyPay;   //Pay per hour.

  public:
    Employee(int initId=0, char [] =0, double initHourlyPay=0.0);  //Constructor.

    bool set(int newId, char [], double newHourlyPay);
    int getId() { return id; }
    const char * getName() { return name;}
    double getHourlyPay() { return hourlyPay;}


};

Employee::Employee( int initId, char initName[], double initHourlyPay)
{
  bool status = set( initId, initName, initHourlyPay);

  if ( !status )
  {
    id = 0;
    strcpy(name, "");
    hourlyPay = 0.0;
  }
}

bool Employee::set( int newId, char newName[], double newHourlyPay)
{
  bool status = false;

  if ( newId > 0)
  {
    status = true;
    id = newId;
    strcpy(name, newName);
    hourlyPay = newHourlyPay;
  }
  return status;
}

const int MAX_SIZE = 100;


int main()
{

    int id;             //Employee ID.
    char newName[21];

    double hourlyPay;   //Pay per hour.


    Employee list[15];  //Array to store


    ifstream masterFile;        //Opens master file.

    masterFile.open("master10.txt");

    int count = 0;
    if (masterFile)
    {
        for (count; count < 2; count++)
        {
            masterFile >> id;
            masterFile.ignore();
            masterFile.get(newName, 21);
            masterFile >> hourlyPay;
            list[count].set(id, newName, hourlyPay);


        }

    }

    masterFile.close(); //Close master file.

    cout << list[0].getId() << "   " << list[0].getName() << "  " << list[0].getHourlyPay();
}

I only changed getline to get and now it can read in the middle of a line with a limit of 20 chars. I appreciate everyone's attention and help.
