Some of them: %, *, /, %=, *=, /=
When a variable is declared as being a pointer to type void it is known as a generic pointer. Since you cannot have a variable of type void, the pointer will not point to any data and therefore cannot be dereferenced. It is still a pointer though, to use it you just have to cast it to another kind of pointer first. Hence the term Generic pointer.
You cannot delete an uninitialized pointer, because there is no allocation for the object, and the pointer contains garbage. That includes the case where you attempted allocation and failed, but deletion is safe in that case because a NULL pointer is "safe" to delete, even though it does not point at anything.
Answergenerally we use simple pointer, void pointer,null pointer, structure pointer. Answerzero or more (unlimited).
No. You cannot throw or catch Null pointer exceptions
A universal pointer is a pointer variable that does not specify the type being pointed at. That is, it can be used to store any memory address regardless of the type of object actually stored at that address. It can be likened to a variable type, but you cannot dereference the memory address without providing some mechanism for determining the actual type stored at that memory address. Generally you would use a universal pointer when you don't actually care what type resides at the address, you are only interested in the address itself. But just as a typed pointer can point to 0 (or NULL), so can a universal pointer, which simply means it points at nothing at all.

Generic pointer of type 'void *' is compatible with any (data-)pointer, but you cannot use the following operators on it: + - ++ -- += -= * -> []

You cannot 'delete a pointer', but you should release allocated memories when they are no more needed.

The correct spelling is operator.
