Answer to Question #50608 in C++ for Umer

Question #50608
Pointers are complicated, so let’s see whether we can make their operation more understandable (or possibly more impenetrable) by simulating their operation with a class. To clarify the operation of our homemade pointers, we’ll model the computer’s memory using arrays. This way, since array access is well understood, you can see what’s really going on when we access memory with pointers. We’d like to use a single array of type char to store all types of variables. This is what a computer memory really is: an array of bytes (which are the same size as type char), each of which has an address (or, in array-talk, an index). However, C++ won’t ordinarily let us store a float or an int in an array of type char. (We could use unions, but that’s another story.) So we’ll simulate memory by using a separate array for each data type we want to store. In this exercise we’ll confine ourselves to one numerical type, float,so we’ll need an array of this type; call it fmemory. However, pointer values (addresses) are also st
