Thread: How do I put this code into custom classes?

I spent an entire week trying to figure out how to do this correctly and I finally got it, only to find that I have to put it into custom classes. Then I spent the entire past week trying to do it but I feel like I am doing everything completely wrong and I just get lists and lists errors.

BTW I am using Dev C++

Here is my code without custom classes.

Code:

#include <cstdlib>
#include <iostream>
#include <fstream>

using namespace std;

int main(int argc, char *argv[])
{
    int itemNumber;
    string itemName;
    float itemPrice;
    string name;
    string adress;
    int telephone;
    int age;
    string employeeId;
    string department;
    int numberOfEmployee;
    int registerNumber;
    int shift;
    int number;
    float saleAmount;
   
    cout<<"1. Employee"<<endl<<"2. Inventory"<<endl<<"3. Sale Interface"<<endl;//MENU
    cout<<"Please enter 1, 2 or 3: "<<endl;
    cin>>number;
   
    if (number == 1) //start employee function
{
    string employeeType;
    cout<< "This program is for cashiers or managers"<<endl;
    cout<<"Please enter the following information:"<<endl<<"Name: ";
    cin>>name;
    cout<<endl;
    cout<<"Adress (with no spaces): ";
    cin>>adress;
    cout<<endl;
    cout<<"Telephone: ";
    cin>>telephone;
    cout<<endl;
    cout<<"Age: ";
    cin>>age;
    cout<<endl;
    cout<<"Employee Id: ";
    cin>>employeeId;
    cout<<endl;
    cout<<"Are you a cashier or a manager?"<<endl;
    cin>>employeeType;
   
    if (employeeType == "cashier")
    {
    cout<<"Register Number: ";
    cin>>registerNumber;
    cout<<endl;
    cout<<"Shift: ";
    cin>>shift;
    cout<<endl;}
   
    else if (employeeType == "Cashier")
    {
    cout<<"Register Number: ";
    cin>>registerNumber;
    cout<<endl;
    cout<<"Shift: ";
    cin>>shift;
    cout<<endl;
}
      else if (employeeType == "Manager")
    {
        cout<<"Department: ";
        cin>>department;
        cout<<endl;
        cout<<"Number Of Employees: ";
        cin>>numberOfEmployee;
        cout<<endl;
    }          
                            
    else if (employeeType == "manager")
    {
        cout<<"Department: ";
        cin>>department;
        cout<<endl;
        cout<<"Number Of Employees: ";
        cin>>numberOfEmployee;
        cout<<endl;
    }
    else
    {
        cout<<"You didn't enter cashier or manager"<<endl;
    }
}//end of employee function

else if (number == 2)//Inventory function start
{
     cout<<"This is where you enter inventory information to be saved."<<endl;
     cout<<"Enter the item number: ";
     cin>>itemNumber;
     cout<<endl;
     cout<<"Enter the item name: ";
     cin>>itemName;
     cout<<endl;
     cout<<"Enter the item price: ";
     cin>>itemPrice;
     cout<<endl;
    
 }//inventory function end
 
 else if(number == 3)//sale interface start
 {
      cout<<"Please enter your total sale amount: ";
      cin>>saleAmount;
      cout<<endl;
      saleAmount=(saleAmount*.06)+saleAmount;
      cout<<"Your total with tax is: "<<saleAmount<<endl;
  } //sale interface ends
 else
 {
     cout<<"INVALID ENTRY"<<endl; 
 }
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

Please help me! I'm going crazy!

First of all this

Code:

if (employeeType == "cashier")
{
    cout<<"Register Number: ";
    cin>>registerNumber;
    cout<<endl;
    cout<<"Shift: ";
    cin>>shift;
    cout<<endl;}
   
else if (employeeType == "Cashier")
{
    cout<<"Register Number: ";
    cin>>registerNumber;
    cout<<endl;
    cout<<"Shift: ";
    cin>>shift;
    cout<<endl;
}

Should be done like this, saving lots of line:

Code:

if (employeeType == "Cashier" || employeeType == "cashier")
{
    cout<<"Register Number: ";
    cin>>registerNumber;
    cout<<endl;
    cout<<"Shift: ";
    cin>>shift;
    cout<<endl;
}

As for the actual question, what kind of class do you want? You want more than one? One class can be

Code:

class myClass
{
    int itemNumber;
    ...
    float saleAmount;
public:
   void employee();
   void inventory();
   void salesInterface();
};

so you have all your variables and your three pseudo-functions. Then you create one object in main and do what you want by calling the three functions. Or sth like that.

Awesome! Thank you so much for responding so quickly. I actually tried the || on those to save lines earlier and it wouldn't work for me because I forgot to type employeeType == for both of them and I decided to just fix it later. So you actually helped one of my other problems without me even asking! =D

Yes, for the most part I am pretty sure I want more than one, I am just not really grasping what goes where etc. What would be the most "professional" way to do it? The assignment just calls to implement classes in general.

Thanks again!

But i say a 'case' for inheritance, check some recent posts most noticeably bubba, dont make extra classes just for hell of it and you can 'compose' your classes to make an elegant solution instead of inheritance for sake of it, i like that talk...
