C++ LANGUAGE

1. Complete the implementation of the classes circle and cylinder as declared in the program cylinder.cpp. Your output file should look like:

p = ( x = 1, y = 2 )

c = ( center = ( x = 1, y = 2 ), radius = 5 )

d = ( center = ( x = 3, y = 4 ), radius = 6 )

e = ( base = ( center = ( x = 1, y = 2 ), radius = 5 ), height = 5 )

f = ( base = ( center = ( x = 1, y = 2 ), radius = 6 ), height = 7 )

g = ( base = ( center = ( x = 3, y = 4 ), radius = 6 ), height = 7 )
