visual studio simple project

this is a simple visual studio project with some data entry menus. required to develop a program in Visual Studio (using C++) that allows creating, viewing and storing information about telephone customers. You will need to author two classes – Customer and Pensioner. Pensioner should be a subclass of Customer. These classes should be in their own files with separate header files. Details are below. Create a third class called Manager. The manager file can contain the main function. The Manager class should contain member functions that read a text file, called [login to view URL], line by line, performing appropriate actions at each line, until the end of the file is reached. You should make no assumptions about the length of the file. A separate C++ file called [login to view URL] should be created to hold the main function. The task of the main function is to instantiate the Manager object and to invoke the member function responsible for reading the file. All of the functionality should be maintained in the appropriate class above.
