C++ Desperately need help!!!

Original Post

Namaste!!! 1. NumDays class Design a class called NumDays. The class’s purpose is to store a value that represents a number of work hours and convert it to a number of days. For example, 8 hours would be converted to 1 day, 12 hours would be converted to 1.5 days, and 18 hours would be converted to 2.25 days. The class will have a constructor that accepts a number of hours, as well as member functions for storing and retrieving the hours and days. The class will also have the following overloaded operators: + Addition operator. When two NumDays objects are added together, the overloaded + operator will return the sum of the two objects’s hours member. - Subtraction operator. When one NumDAys object is subtracted from another, the overloaded - operator will return the difference of the two object’s hours member. ++ Prefix and postfix increment operators. These operators will increment the number of hours stored in the object. When incremented, the number of days will be automatically recalculated. -- Prefix and postfix decrement operators. Theses operators will decrement the numbers of hours stored in the object. When decremented, the number of days will be automatically recalculated. Last edited: 12-Apr-11 03:56 PM

Try this one buddy

class numDay

{

 int hour;int day;

void hour{

if(hour>=8)

{

day++;

cout<<day;

}}

void day

{

if

{

hour=hour-8;

cout<<hour;

hour++;

}}

}

main

{

numday a,numday b;numday c;

c.hour==a.hour-b,hour;

c.day==a.day-b.day;

cout<<c.hour();

cout<<c.day();

end

}

Namaskarr!!

class NumDays

{

      int hours;

      1) create constructor with numHours as parameter and set it to hours

       2) create getter and setter for hours

       3) make method getDays() something like below

        public float getDays() {return hours/8;}

      4) overload operators + something like below

int::operator+(NumDays &rhs)

 {

      return this.hour + rhs.hour

 }

overload other operators similarly

this is in java, 

// a bit left...complete by urself

package demo.test;

public class NumDays {

    private int days;

    public NumDays(int hours){

        if(hours <=8){

         days=(hours-(hours-1));

         days = hours;  

        }   

    }

    public int getWork_hours() {

        return days;

    }

 }

//test class

package demo.test;

public class TestNumDays {

  public static void main(String[]args){

      NumDays nd = new NumDays(8);

      System.out.println("No of Days:\t"+nd.getWork_hours());

  }

}

int NumDays::operator -(NumDays & right)

     return total_Hours;

}

int NumDays::operator ++(int)

{

     int Self=hours;

	 hours++;

     day=hours/8.0;

     return Self;

}

int NumDays::operator ++()

{

     hours++;

     day=hours/8.0;

     return hours;

}

int NumDays::operator --(int)

{

     int Self=hours;

     hours--;

     day=hours/8.0;

     return Self;

}

int NumDays::operator --()

{

     hours--;

     day=hours/8.0;

     return hours;

}

i think i am doing right up to here.

This is what so far i got. i need  a int main...program to call this function. 

thanks for help.
