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.
