Sometimes, you need a different type of array conversion,For example, the Int16 type of data that is read from the capture card needs to be stored in the database OLE object and converted into a byte type.Here are two functions to complete the

" overloaded "Features that are overloaded by member functions:(1) The same range (in the same class);(2) The function has the same name;(3) different parameters;(4) The virtual keyword is optional.CoverageOverrides refer to a derived class function

The const int p indicates that p is a constant immutable (there are ways to change it, not here)So it's natural to think that the const int *P is p as a pointer immutable? (that is, p cannot change direction?) ）However, it is not so const int *p
