C$++$ Define the following functions:

CalcBaseArea$()$ has one double parameter as a cylinder's radius. The function returns the area of the cylinder's base as a double. The area of the base is calculated by:

CalcSurfaceArea$()$ has two double parameters as a cylinder's radius and height. The function returns the cylinder's surface area as a double, and uses the CalcBaseArea$()$ function to calculate the cylinder's base area. The surface area is calculated by:
