Or undefined behavior.<p>I guess it can be summed up as: C++ is extremely good at making people <i>think</i> they&#x27;re writing safe programs.<p>This feeling of safety is virtually always incorrect in the case of large-scale software, and the huge stream of memory-related vulnerabilities that virtually all popular network-facing C++ applications have and continue to have is proof of this. There is no reasonable way to argue against this; the fraction of popular network-facing C++ software written by a large team that have had memory safety problems rounds up to 100%.
