C++ allows the programmer to assign the same name to two or more functions. The way to do this sort of thing where you want to be able to "pass in" the method that you want to use would be to use the polymorphism that VB has, and use a separate Class for each implementation. That means on the command prompt you would write slope Equation(4,5,6). You also then have to worry about passing the function handles around as arguments to make sure you have them where you need them. Finally add(r2, num4) is evaluated and its result is printed. In general, two functions in a single program cannot share the same name. 4 pts (CO 6) What statement allows you to call the print_name(name) function from a module named address that has been imported with this statement?
