Why do computers have byte-addressable memory, and not 4-byte-addressable memory (or 8-byte-addressable memory for 64bit)? Yeah, I see how it could be useful sometimes, it just seems inelegant and excessive. Are the advantages substantial, or is it really...

Processors actually do access memory in quantities of 64-bit (x86 did since Pentium or so); 64-bit processors often have a 128-bit bus.

In C++:
On stack, a simple variable is assigned a memory address so that we can use pointer to contain this memory to point to it; then is a pointer also assigned a memory address? if yes, we can have pointer of pointers now?
Thanks!

Pointer is just a variable (memory location) that stores the address of other variables.

Something like this would work.
Use the %p formatter to get the address of an object as a string.

This way you can then use the data in managed code with * and & just like C .
You can use Marshal.Copy to copy the data from native memory into an managed array.
Will allow you to use the memory handle from the ActiveX component.
