Does pointer = &pointerToMyObject[5]; do the same as pointer = pointerToMyObject + 5 * sizeof(MyClass); where pointerToMyObject points to the 10th element of a large enough array of type MyClass?

you dont need to use sizeof(), incrementing a pointer will increment it by the size of the type its pointing to.

Thanks. Then that explains some weird behaviour and memory-related crashes :D
