Question

Please help me on C++ using code blocks

Define the class rectangleType with data members: length and width of type double. Include the following public member functions:
? setDimension(double l, double w); getLength(); getWidth(); area(); perimeter(); print();
? setLength(double l); to set the length and a reference to the object (the address of the object) is returned.
? setWidth(double w); to set the width and returns the resulting object..
? operator+(); to add the dimensions of 2 rectangles and to return a reference to the resulting object.
? operator++(); to post-increment the dimensions of 2 rectangles and to return a reference to the resulting object.
? Operator==(); to return the result of equating 2 rectangles.
? Operator!=(); to return the negation of operator==().
? Operator>(); to return the result of comparing 2 rectangles for greater than relationship.
? Operator<(); to return the result of comparing 2 rectangles smaller than relationship.
? Constructor with the 2 default parameters set to 0 and have the same names as the data members (i.e. : length and width).

1.Study the testDriver and sample output results above and then explain the difference between Line#1 and Line#2.
2. Study the testDriver and sample output results, then explain why the last results for r1 and r4 are similar.

Explanation / Answer

class Rectangle

{

public:

double length, width;

public:

void setDimensions(double a,double b)

{

length = a;

width = b;

}

void area()

{

double area = length*width;

}

void perimeter()

{

permeter = 2*(length + breadth);

}

void print()

{

cout<<"length:"<<length<<"width:"<<width<<"area:"<<area<<"Perimeter:"<<perimeter<<endl;

}

Rectangle void operator +(Rectangle r1,r2)// implementing operator overloading

{

Rectangle r3;

r3.length = r1.length + r2.length;

return r3;

}

Rectangle void operator ++(Rectangle r1)// implementing operator overloading

{

Rectangle r4;

r4.length = r1.length + 1;

r4.width = r1.width + 1;

return r4;

}

}

public void main()

{

Rectangle r1, r2, result1, result;

r1.getDimensions(5,7);

r2.getDimensions(7,9);

result1 = r1 + r2;

result1.area();

result1.perimeter();

result1.print();

result = r1++;

result.area();

result.perimeter();

result.print();

}
