WebArray bounds checking requires two things: the offset calculations to check the array bounds, and the array itself to have bounds. In C, arrays have this nasty habit of decaying into pointers. Once that happens, the length of the array is no longer known to the compiler. WebThe most direct way to create a multidimensional array in C++ is to statically allocate it, which we do by including the size of each of its dimensions as part of its declaration. Because statically-allocated arrays have to be allocated at compile time, the bounds of each dimension must be constants (or, at the very least, constexprs, i ...

Without departing too far from the basic style of C and raw arrays, you can use C++ and an std::vector with [i] replaced by .at (i), and get bounds checking.
