Help Wanted :)

Hey guys, I need a little help :)


1. Write a class "Bulb" which has a private member - type bool!- "Balance", default constructor which sets the state to FALSE and public methods "PushTheButton" that will turn on and off the lamp and "Check" which will print out "Light" or "Dark" depends on the current state (0-dark, 1-light). Create an object "Turning" of class "Bulb" and turn it on and off several times.

2. Write a class "Employees" which has private data members: "path", "age" and "wages". Write constructor which initialized data members while creating a object. Write destructor which print out "Destructor employees - fired". Write an access method that can change some of the data members and methods that can get their value. Write a "friendly" function that calculates how much
employee has earned.
Note: the function accepts a reference to an object of class "Employees".
You need to calculate how much employee earned during his work
(months*number of working years*wages)

Apparently you missed this announcement at the top of the page.

yup, i missed that part.. i'm one of those people who don't read rules :) but anyway, it makes more fun if you do by yourself :) and btw, i didn't need for homework or something like that..i was just interested how would someone else do the same program. :)

Code:

---

#include <iostream>
using namespace std;

class Bulb{
   
      private:
              bool Balance;
      public:
        Bulb(){Balance=false;};
            void PushTheButton (){
            Balance=!Balance;
          }
            void Check (){
                  if (!Balance)
                    cout<<"Dark!"<<endl;
                  else
                      cout<<"Light!"<<endl;
            }
};

int main (){
    bool Balance;
 

    Bulb Turning;
    Turning.PushTheButton();
    Turning.Check ();
    Turning.PushTheButton();
    Turning.Check ();
   
    system ("pause");
    return 0;
}

---

Code:

---

#include <iostream>
using namespace std;

class Employees{
  friend float Earning (Employees&);
private:
  float path;
  float age;
  float wages;
public:
  Employees (float,float,float);
  ~Employees();
  float Path(){return path;}
  float Age () {return age;}
  float Wages () {return wages;}
};

float Earning (Employees &earned){return (earned.path*earned.age*earned.wages);}
 
//constructor
  Employees::Employees(float Path,float Age, float Wages){
    path=Path;
    age=Age;
    wages=Wages;
  }

//destructor
  Employees::~Employees (){
    cout<<"Destructor employees  - fired!"<<endl;
  }

  int main (){

    Employees A(12,5,3000);

  cout<<"Employee has earned:"<<Earning (A)<<endl;
 

    system ("pause");
    return 0;

  }

and btw, sorry for my "not reading" :)

Uh hu. You might want to read this recent thread.

1. i'm not a boy :)
2. yes,i'm student on faculty for electrical engineering , branch - computer engineering.
3. google.com is my best friend.
4. believe it or not - i didn't come to beg for my homework or don't know what :)
5. "hey guys, i need a little help" - i should use another words, then maybe you wouldn't think that i come to beg :D
6.. all in all , i don't know why i'm typing all this things, when you will think so or so what do you want to think, AND when you wont reconsider about any other solutions :) :)

Since those are two specific exercises, I don't think anyone could code them otherwise, except from "main()" and indentation, that is.

Bulb looks OK, except for indentation. One thing, though. CheckButton should be const.

For Employees, you should have a look at this.
Earning also does not need to be a friend function for the class. It can simply use the public interface to get the required data. It should also take a const reference instead of a reference. Public interface get functions should be const. Indentation should also be fixed.

OK. Just bear in mind that there are a fair few boys who try to elicit homework answers by pretending to be girls.

There are also some pretty good female programmers around here, but I won't deny them the right of introducing themselves as they see fit.

A female electrical engineer, eh? A rare beast, but hopefully one becoming less rare.

My condolences. My two best friends are a person and a dog. Incidentally, both are female.

It will probably help if, as you learn, you also give something back. Even if your advice to others isn't perfect, the attempt is important (even the most knowledgeable folks here get it wrong sometimes, and are picked up by someone else).

The attempt to help someone is often the best way that you can learn too.

The question you were given is pretty specific. There isn't much scope for considering other solutions.

If you want people to really look at options, don't nail down your question so much.
