minus-squarerhpp@programming.devlinkfedilinkarrow-up11·1 year agoStill false, thanks to compiler optimizations. Remember that integer overflow is UB. (unless you’re using unsigned int or a programming language which strictly defines integer overflow, possibly as an error) P.S.: Assuming this is C/C++
