To forestall slicing, as the typical copy functions will duplicate just the foundation part of a derived object.
Comparing the efficiency of a set-sized array allotted within the stack from a vector with its elements around the absolutely free retail store is bogus.
Most compilers currently alert about basic instances and has the knowledge to carry out a lot more. Take into account any pointer returned from a functionality suspect.
