Partially revert "Cleanup: use post increment/decrement"

This partially reverts commit 0b2d1badecc48b5cbff5ec088b29c6e9acc5e1d0

Post increment can deep-copy for C++ iterators, while in my own checks
GCC was able to optimize this to get the same output,
better follow C++ best practice and use pre-increment for iterators.
