CCC-Assignment 4 C Rectangle Solved

Please design a class CRectangle with 2 CPoint objects. These 2 CPoint objects denotes the points ot the top left corner and lower right corner. Please calculate the area of the rectangle.

Notes: Each constructor and destructor of all designed classes should output "*** is called”.

The main function is given as follows：

int main()

{

int a=1, b=1, c=6, d=11;

cout<<"# Define p1 ######"<<endl;

CPoint p1;

cout<<"# Define p2 ######"<<endl;

CPoint p2(10,20);

cout<<"# Define rect1 ######"<<endl;

CRectangle rect1;

cout<<"# Define rect2 ######"<<endl;

CRectangle rect2(p1, p2);

cout<<"# Define rect3 ######"<<endl;

CRectangle rect3(a, b, c, d);

cout<<"# Define rect4 ######"<<endl;

CRectangle rect4(rect2);

cout<<"# Calculate area ######"<<endl;

cout << "rect1 area:" << rect1.GetArea() << endl;

cout << "rect2 area:" << rect2.GetArea() << endl;

cout << "rect3 area:" << rect3.GetArea() << endl;

cout << "rect4 area:" << rect4.GetArea() << endl;

return 0;

}
