Is a pointer 4 bytes?

Consider a compiler where int takes 4 bytes, char takes 1 byte and pointer takes 4 bytes. Explanation: Size of an array is number of elements multiplied by the type of element, that is why we get sizeof arri as 12 and sizeof arrc as 3. Size of a pointer is fixed for a compiler.

Are pointers 4 or 8 bytes?

For x86 architectures or possibly the more accurate term, IA-32 (see IA-32 ), a pointer is 32 bits (or 4 bytes). For x64 architectures (see x86-64 ), pointers are 64 bits (or 8 bytes). There are other processor architectures that are older.

What is size of a pointer?

Usually it depends upon the word size of underlying processor for example for a 32 bit computer the pointer size can be 4 bytes for a 64 bit computer the pointer size can be 8 bytes. So for a specific architecture pointer size will be fixed. It is common to all data types like int *, float * etc.

Do pointers have a size?

Function Pointers can have very different sizes, from 4 to 20 Bytes on an X86 machine, depending on the compiler.

Are all pointers the same size?

Generally yes, All pointers to anything, whether they point to a int or a long or a string or an array of strings or a function, point to a single memory address, which is the same size on a machine.

Is a pointer just a number?

You cant access a through b . Then how is your question suitable. In b , address of a is treated as only value not a address , because of b is variable not a pointer.. Even it prints 101010 , this program is not a generic.

Can a pointer point to itself?

Yes, a pointer can contain the position of a pointer to itself; even a long can contain the position of a pointer to itself.

Why the size of pointer is 8 bytes?

Size of Different Data Types The reason is, the size of data types vary according to the processor used. For example, the long data type in a 32-bit processor will be 4 bytes while it will be 8 bytes for a 64-bit processor.
