What Is The Difference Between A Copy Constructor And An Overloaded Assignment Operator?
Language: C++
Next a thirst level (as double value) should be added to the properties of a critter. Add a new
constructor that takes five parameters for setting all properties of a critter.
Make also sure that the existing constructors will still work. For the existing constructors, the
thirst level should be set to the same level as the hunger level. Your existing testcritter.cpp
must still be able to run in its unchanged form. So the already existing constructors need to
support the change. Name the files Critter.h, Critter.cpp and testcritter.cpp.
Finally, you should adapt the print method for printing on the screen also the value of the thirst
level as a double. The client program testcritter.cpp may contain one additional line, where
the constructor taking five parameters is being called.
You can assume that the setting values are always valid.
