A pointer is an object that contains the address of another object, hence the term pointer, meaning that one object points to another.

generic pointer is a pointer that can not be dereferenced i.e one type pointer can not be assigned to another type.
Yes, C++ supports function pointers.
An address in C or C++ is the location in memory of an object or function. An address is the contents of a pointer, as opposed to the contents of the memory location pointed to by the pointer.
A pointer is a variable that holds an address in memory. int * pPointer = new int; This code creates a pointer to an integer, and assigns it an address of an integer object on the heap.
Multiplication is yet another thing, what you should never do with pointers.

Address of the current object.
Yes, C++ supports function pointers.
a pointer that is not pointing to anything
An address in C or C++ is the location in memory of an object or function. An address is the contents of a pointer, as opposed to the contents of the memory location pointed to by the pointer.
The function ftell returns the position of the file pointer for a file.

The this operator in C++ is a compiler generated pointer to the instance of an object, accessible from within a method of that object.
A pointer in C++ is the same as a pointer in C -- it is a variable that is used to store a memory address and which allows indirect access to that memory address. When a pointer is not in use, it must be zeroed or nullified by assigning the NULL value, thus preventing indirect access to invalid memory.
A double pointer is a pointer which points to another pointer which points to an object.For example:Foobar** foobar = NULL;This means that somewhere in memory, the class foobar has been created. The variable 'foobar' now points to a pointer to that memory. However, in this example, the pointer is created as 0.
