In C++, a pointer is a variable that contains a memory address. For instance, if x contains the address of y, then x is said
to "point to" y. Pointers and arrays are strongly related, and they are interchangeable in many cases. For instance, a
pointer that points to the beginning of an array can access that array by using
either pointer arithmetic or array-style indexing. Note that the general form of a pointer variable
declaration is: There are two special operators that are used with pointers: i) * and ii) &. Note that DM does not support such pointer variables.
