are pointers of integer or unsigned datatype?
397
There are majorly four types of pointers, they are: Null Pointer. Void Pointer. Wild Pointer.
A pointer is a variable that stores a memory address. Pointers are used to store the addresses of other variables or memory items. Pointers are very useful for another type of parameter passing, usually referred to as Pass By Address.
No. They're pointers, whose size is system-dependent and whose only compatible type is void*.

Pointers are of pointer type. If you're asking about how pointer values are represented in memory, that really depends on the platform. They may be simple integral values (as in a flat memory model), or they may be structured values like a page number and an offset (for a segmented model), or they may be something else entirely.
