c++ - Pointer alignment -

Can someone explain (by giving an apppip link for example) What does the indicative alignment in C ++ mean? Thank you.

This is also good -

A memory address A, n -Byte coalition is called when n is the power of two and one is multi-byte bytes. In this context, one byte is the smallest unit of memory access, i.e. each memory address specifies a different byte.

In logging an en-byte, log2n will be less-important zero.
