Question

Lab 3.1

Create your objects in the stack (not on the heap). Add a friend function, kilotopound, which will convert kilograms to pounds. Change your weight mutator to ask whether weight is input in kilograms or pounds. If it is kilograms, call the friend function kilotopound to convert it to pounds and return pounds.

There are 2.2 pounds in one kilogram.

Create an object on the stack with the following information:

   

uld – Container

abbreviation - AYK

uldid – AYK68943IB

aircraft - 737

weight – 1654 Kilograms

destination – PDX

Output the contents of your object.

Lab 3.2

Utilizing Lab 3.1 code, add a copy constructor.

Create an object on the stack using the following data:

uld – Container

abbreviation - ABB

uldid – ABB31545IB

aircraft - 737

weight – 1156

destination – BUR

Copy the first object using a copy constructor. Output the contents of both objects.

       cout<<"aircraft -- "<<aircraft<<endl;
       cout<<"weight -- "<<weight<<" Kilograms"<<endl;
       cout<<"destination -- "<<destination<<endl;
  
   }
  
   //friend function kilotopound
   friend void kilotopound(Item );
};

void kilotopound(Item I)
{   //weight*2.2 = weight in pounds
   cout<<"Weight in pounds is: "<<I.weight*2.2<<" Pounds "<<endl;
}

int main()
{
   //this will create item on the stack , new keyword
   //declares memory on the heap
   Item I;
  
   //setting all values for the members
   I.uld="Container";
   I.uldid="AYK68943IB";
   I.abbreviation="AYK";
   I.aircraft=737;
   I.weight=1654;
   I.destination="PDX";
  
   //printing data
   I.print();
   //printing weight in pounds using kilopounds
   kilotopound(I);
   return 0;
