What gives here?  

This is so trivial I suspect that it is some sort of homework assignment.

Homwork with a menu?  Probably not.   possibly not?

Blocker, if this is for school, we cannot _give_ you the answer, but we can provide limited assistance.  

If it is not for schoole, we still can't provide the answer--in this case.  This is because a standard C++ program can't have menus.  You need to use non-standard OS-specific features to have menus, like features in the Windows API.  But those sorts fo things are not available in DOS.  We can show you how to read from a file, but the menu part is (nearly) impossible to do  (from DOS).

You can use menus from DOS by using turbo vision from Borland. As for reading the txt file, you should use the fstream class.

What do you want to do about the menu part?  Realistically you can't have a menu in DOS (not without lots of work, or pehpas with turbo vision, if you have it, and now how to use it.)

to read a file and display it, just do.

fstream Fil("c:\somefile.txt",ios:in);

while (true)
{
   char Chr;
   Fil >> Chr; // Read a character from the file.
   if (Fil.eof()) // If at the end of the file, then
       break; // stop processing.
   cout << Chr; // Write the character to the screen.
}
