Assignment 10

Assignment 10 - Geometric Solids

due December 1st

This assignment will give you practice with inheritance.

Use the following 5 classes for your solution

Class	Description
Location	Represents the x-y coordinates of Shape class objects Should contain two doubles Add an overloaded insertion operator for this class
Shape	Base class Should contain 3 members: a Location, color (string) and type (string) Add an overloaded insertion operator for this class
Square	Derived from Shape Add an area function
Circle	Derived from Shape Add an area function
Triangle	Derived from Shape Add an area function

Additional Requirements

Use constructor initializers for all constructors
Use a named constant for pi
Use the following main function

int main()
{
    cout << setprecision(2) << fixed << left;
    Shape sh(4,5,"red");
    cout << sh << " area = " << sh.area() << endl;
    cout << endl;

    Square sq1(1.0,2.0,3.1,"green");
    cout << sq1 << " area = " << sq1.area() << endl;
    Square sq2(1.5,2.5,3.2,"lime green");
    cout << sq2 << " area = " << sq2.area() << endl;
    Square sq3(6.7,0.0,3.3,"chartreuse");
    cout << sq3 << " area = " << sq3.area() << endl;
    cout << endl;

    Circle c1(0.0,2.0,3.4,"blue");
    cout << c1 << " area = " << c1.area() << endl;
    Circle c2(0.0,2.0,3.5,"peacock blue");
    cout << c2 << " area = " << c2.area() << endl;
    Circle c3(0.0,2.0,3.6,"sapphire");
    cout << c3 << " area = " << c3.area() << endl;
    cout << endl;

    Triangle t1(1.4,2.0,1.1,1.2,1.3,"red");
    cout << t1 << " area = " << t1.area() << endl;
    Triangle t2(1.23,2.0,3,4,5,"cardinal red");
    cout << t2 << " area = " << t2.area() << endl;
    Triangle t3(4.56,2.75,1,1,1,"crimson");
    cout << t3 << " area = " << t3.area() << endl;
}
