Write the definition of a class METROPOLIS in C++ with following descriptions:

Private Members:
-MCode // Code in Integer
-MName // Name in String
-MPop // Population in Long
-Area // Area coverage in Float
-PopDens // Population Density in Float
-CalDen() // Function to calculate Density as MPop/Area

Public Members:
-Enter() // Function to enter values of MCode, MName, MPop, Area
// and call Function CalDen
-ViewAll() // Function to display all the data members also display 
// message Highly Populated Area if the density is more than 12000
