Is the size of the pointer fixed or not?
Does the size of the pointer depends on the parameters like 16-bit compiler or 32-bit compiler?

For a given platform (computer) and a given compiler, the size of a pointer is fixed.Originally posted by shanthisagar
There are a lot of different computers out there and a lot of different compilers so
expect to find a lot of different pointer sizes.
The 16-bit and 32-bit name suffixes don't say much about the size of a pointer;
e.g. the good ol' AS/400 has a 32 bit wide processor but pointers can be as
large as 256 bits.

Adding to what JosAH has said, I would like to add that a pointer is just a variable. However, it is a variable that can only contain an address. Since addresses for a given operating system are all the same length, the pointer variables are all the same size.Comment
