Below is some code for a
rectangle class that needs to be completed. The goal is to code the
class so that it works without
changing the main program.
Starter Code
This is the starter code. Declare
the member functions, define the accessors and fill in the member
function code.
#include
<iostream> using namespace std;
// rectangle has a vertical height and horizontal
width
// The class below is a
rectangle. It has two private
// data members: height
and width.
// TODO: Complete the class declaration and definition. class
rectangle {
public:
//
TODO: declare a default constructor that sets height & width to
1.
// TODO: declare
member function void add
//
@param int height, int width
//
TODO: declare member function void set
//
@param int height, int width
// TODO: declare
member function void draw
// TODO: define
accessor for width (remember it must return int)
// TODO: define
accessor for height
// TODO: define a function to tell if a rectangle is a square
private:
int
width, height;
};
//
TODO: Implement a default constructor to initialize height and width
to 1.
// The default constructor executes when the object is first
declared.
// It is a function with the same name as the class
(see below).
// It also has no return type
rectangle::rectangle()
{
}
//
TODO: Implement add to increment the dimensions
//
add the given addHeight to height and addWidth to width
void
rectangle::add(int addHeight, int addWidth)
{
}
//
TODO: Implement set to overwrite the data
members void rectangle::set(int h, int
w)
{
}
//
TODO: Implement draw to draw a rectangle using '#'
characters void rectangle::draw()
{
}
// TODO: Define getWidth and getHeight
//
TODO: Implement isSquare to indicate if a rectangle is a square. int
main()
{
// Declare 2 rectangles rectangle r1, r2;
// Print unit
rectangle
cout << "unit rectangle" << endl; r1.draw();
// Set, print dimensions and draw r1.set(4, 3);
cout << "r1 is " << r1.getHeight() << "
x " << r1.getWidth() << endl;
r1.draw();
// Assign, increment, print dimensions and draw r2 = r1;
r2.add(3,
4);
cout << "r2 is " << r2.getHeight() << "
x " << r2.getWidth() << endl;
r2.draw();
if (r2.isSquare())
cout << "r2 is a square" << endl; else
cout
<< "r2 is not a square" << endl;
return
0;
}
Program Output
unit
rectangle #
r1
is 4 x 3 ###
### ### ###
r2
is 7 x 7 ####### ####### ####### ####### ####### ####### #######
r2 is a square
