Extracted text: Language: C++ Create a class named City. Assume that a city has a name, a number of inhabitants, a mayor and an area (in km²). Then create three instances of this class: Bremen, Paris and London. Provide suitable setter and getter methods for each of these properties. The class declaration has to be placed into City.h, the class definition has to be placed into City.cpp and the test program where the instances are created has to be in testcity.cpp. You can set the needed data from the main () function by initialization or read it from the key- board.
