Question

In C++ write a simple menu program that displays a menu for the user in an object-oriented technique. The menu should keep showing up until the user chooses to quit. Also, there is a sub-menu inside a menu. The user should get at least a line displayed after he or she chooses that particular option meaning if the user presses 1 for the read actors from the file. The output can look like "reading actors from a file" and then display two other options a and b inside it, similar for sub menus aswell. Some of it has a menu inside a sub-menu as well. Need to submit one .h file with class and other .cpp files with implementation. The user interference will look like this.
