The actual bit representation of an unsigned number is often using a twos complement representation, thus the values may appear 'bigger' at the bit level than what we would expect as programmers. In order to fix this, we can use -Wall to warn us of such conversions, or otherwise use a C++ 20 feature like std::cmp_greater in the utility header (and associated comparisons) to write more stable code. ►YouTube Channel: https://www.youtube.com/c/MikeShah ►Please like and subscribe to help the channel!
