Following the lecture slide :

Giving a bass-class Shape and 3 derived class : Triangle, Rectangle, Circle

You need to calculate the area and the perimeter of each shape.

note : You need to do some basic check: if the given information cannot form a shape (e.g. height of the rectangle is negative number....etc), then the area and perimeter would be both 0)

Input

There are only 3 shapes in this problem :

• Triangle, following by its 3 edges. (e.g. Triangle 3 4 5)
• Rectangle, following by its width and height. (e.g. Rectangle 5 7)
• Circle, following by its radius and the value of pi. (e.g. Circle 2 3.14)

Output

Ouput the total area and perimeter of all the shapes.

Description

Warning: You are not allowed to use malloc and free

Giving a bass-class Shape3D and 4 derived class : Sphere （球體）, Cone （圓錐）, Cuboid （長方體）, Cube （立方體）

You need to calculate the volume of each shape.

PS:

V of Sphere: V = 4/3 π r³

V of Cone: V = 1/3 π r² h

 

note : Remember to do some basic check, if the input is illegal (e.g.  length < 0, pi < 0 .....)  then the volume should be 0.

You don't need to consider the scenario like Cuboid -1 -2 3, volume would be 0 instead of 6.

Hint1: Be careful the type of volume is double.  4/3=1 (int),  so it should be 4.0/3.0

Hint2: You only need to implement the constructors.

Hint3: Note that Cube inherited Cuboid not Shape3D.

 

 

Input

There are only 4 shapes in this problem :

• Sphere, following by its radius and pi. (e.g. Sphere 30 3.14)
• Cone, following by its radius of bottom plane, height and pi. (e.g. Cone 3 100 3.14)
• Cuboid, following by its length, width and height. (e.g. Cuboid 2 3 7)
• Cube, following by its length. (e.g. Cube 2)

Output

Ouput the total volume of all the shapes.

Description

Giving basic information of some shapes, you need to draw them on the Cartesian coordinate system and calculate the total area.

PI has already defined in function.h.

Input

There are only 2 shapes in this problem : 

1. R (Rectangle), followed by 4 points. Each point represent 1 vertex of the rectangle, with the format (x, y).

2. C (Circle), followed by 1 point represent the centre of the circle, and a number of its radius.

If the radius is negative, set it to 0.

e.g., the result of sample input would be like :

Output

Output the total area of all the shapes.
