The number of bytes occupied by the pointer is related to the number of processor bits. A 32-bit processor is 4 bytes. Although you may have a 64-bit processor, it depends on whether you are a 64-bit program, so as long as int is 4 bytes, then the pointer is still 4 bytes
The pointer is 4 bytes in 32-bit and 8 bytes in 64-bit. 4 bytes can represent up to 4G.
The pointer is like a house number. Whether it is a large villa or a small store, there is no difference in the house number. It only represents an address and has nothing to do with the content of the address
The pointer points to the address. As a 32-bit machine, the address is 4*8=32 bits, that is, the pointer size under a 32-bit machine is 4; If it is a 64-bit machine, then the address It is 8*8=64 bits, that is, the pointer size under the 64-bit machine is 8;

The pointer saves an address, not any other data. . . So the size is fixed
The pointer is 4 bytes in 32-bit and 8 bytes in 64-bit.
4 bytes can represent up to 4G.

As mentioned above, the pointer is like a house number. No matter how large a house it is pointing to, the house number always has 4 digits.
