Answer to Question #218435 in C++ for Nikita

Question

struct Module {string moduleName; string moduleCode; string lecturer; int nrStudents} Turn the Module struct into a class. The class should have member variables for all the values in the corresponding struct. Make all the member variables private. Include public member functions for each of the following: a default constructor that sets the string member variables to blank strings, and the int member variable to 0; an overloaded constructor that sets the member variables to specified values; member functions to set each of the member variables to a value given as an argument to the function; member functions to retrieve the data from each of the member variables; Test the class in a program that instantiates an object of class Module. The program should then input values for the object, and use the mutators to assign values to the member variables. Use the accessors to obtain the values of the object's member variables and display those values on the screen.
