Question

(Classes and Objects)

Design a class named Box. The class should have the following private members:

width - A double member variablethat holds the width of the box.

length – A double member variable for holding the length of the box.

height – A double member variable of type double that holds the height of the box.

In addition, provide the following member functions with full (inline) implementation.

a) A default constructor that sets all member variables to 0.

b) A constructor that accepts width, length and height and initializes the member variables appropriately.

c) A copy constructor

d) An appropriate set and get functions for width, length and height.

Answer 1

Thanks for the question. Below is the code you will be needing. Let me know if you have any doubts or if you need anything to change.

If you are satisfied with the solution, please leave a +ve feedback : ) Let me know for any help with any other questions.

class Box{
   private:
       double width, length, height;
   public:
       Box();
       Box(double w, double l, double h);
       Box(const Box& b);
      
       void setWidth(double w);
       void setLength(double l);
       void setHeight(double h);
      
       double getWidth() const;
       double getLength() const;
       double getHeight() const;
};

Box::Box(): width(0), length(0), height(0){
}
Box::Box(double w, double l, double h):
   width(w), length(l), height(h){
}
  
Box::Box(const Box& b){
   width = b.width;
   length = b.length;
   height = b.height;
}

void Box::setWidth(double w){width =w;}
void Box::setLength(double l){length =l;}
void Box::setHeight(double h){height=h;}

double Box::getWidth() const{return width;}
double Box::getLength() const{return length;}
double Box::getHeight() const{return height;}
