does a pointer also occupy memory space

a pointer is an like a normal variable that stores the address of another variable in it as a value.it is also called as reference variable,which points the memory location.yes like other variables which occupies memory location,it also occupies memory location

yes, a pointer is a normal variable, if you don't understand this, think in this way: we can get the address of a pointer variable, so since it has address, it is a variable

A pointer has the address of a variable stored. It has to occupy space, because it has to store the address.

Pointer does not occupy any space. What you mean may that pointer variable.... Am I right? If yes then Pointer variable occupies the memory space of an int.

well i don't think a pointer is occupying a single memory, and you are actualy rite that how can they implement without memory...lol

A pointer is actually a variable that contains memory locations. Pointer arithmetics decide by how much the value of a pointer increases in one go. For example, an integer pointer increases by two(four) bytes (depending upon implementation) at every increase. Yes, pointers do occupy memory. But it is not the data-type that decides the memory-size of a pointer variable but the type of pointer. There are three type of pointers- Near, Far and Huge. Near pointers are used for referencing memory inside the program. Far and huge are used to refer the memory outside the range of program. Near is 16-bit, far and huge are 32-bit. The difference between far and huge is that huge is limited in its operation. And these limits can be overcome using huge pointers.

ya thanks dear.................. i also had this question and was in confused thanks a lot...

pointers does occupy space in the memory as it has to store memory information and data both.

Pointer is also a variable,is having some special characteristics.i.e.It can store the address of another variable of same. for example int*p; this pointer can store only integer variables addresses only.u can't store the char,float variables addresess. int x=10;char ch='a'; u can write p=&x;but u can't write p=&ch; if it is int it takes 2bytes memory(depends on the compiler).if char takes 1byte etc....

Yes, it does occupies 2 bytes of memory in a 16 bit system and 4 bytes in a 32 bit sysytem
