My point was that in C++ (and others) you can completely prevent this entire class of errors by using the standard containers. std::string, just like std::vector and std::array provide the checked access methods which will prevent buffer overflows when used.

Almost every language other than C lets you access elements of a container safely, and oftentimes even the default methods for access are safe! In C++ there are compiler flags that make operator[] safe by default for all of the std containers too.
