❔ unsafe pointer operation

hi. im trying to rewrite code from other c# project to restore the sanity back. there is this one part that i dont quite understand:

byte[] arr = ...;
byte* buffer = arr;
var x = *buffer++; // actual line is much more complicated operations than this

byte[] arr = ...;
byte* buffer = arr;
var x = *buffer++; // actual line is much more complicated operations than this

what does the *buffer++ do? is it equal to buffer[index++] or buffer[index]++. thanks.

it looks like this gets an element in the array every time you increase the pointer, it points to the next element

This is not an acceptable response. Please refrain from meaningless contributions.

it's equivalent to buffer[index++] yes it's just that you don't keep the original base pointer
