Demonstrate your class works with a main() function that instantiates an array of three Rectangle objects, one for each room of a house, using the initializer list below. Then, use your setName() function to fix the name of “Offce” to “Office”. Finally, tell the user the name and area of each room, and the name of the room with the largest area.
Implement the Rectangle class as discussed this week. Use the class declaration below. Your job is to implement the functions. Implement the missing functions yourself.
class Rectangle
{
private:
double width;
double length;
char *name;
void initName(char *);
public:
//constructors
Rectangle();
Rectangle(double, double,
char*);
//destructor
~Rectangle();
void setWidth(double);
void setLength(double);
void setWidth(char *);
void setLength(char *);
void setName(char *);
double getWidth() const;
double getLength() const;
void printName() const
{ cout << name; }
};
A few notes on the functions:
- initName(char *): this is a private member function. It should be the only function which dynamically allocates a char array to hold the name.
- setName(char *): this is a public member function which changes the name of the rectangle to a new name. It does not dynamically allocate memory, it only changes name.

Rectangle house[] = { Rectangle(10, 12, "Kitchen"),
Rectangle(20, 20, "Bedroom"),
Rectangle(8, 12, "Offce") };
