Questions and codes

The following program, Because there are data members of the pointer type, you need a constructor that can complete the deep copy. Please supplement the full constructor and destructor (others do not need to move). Where the constructor completes the following three tasks:
(1) assigns a value to each member function, in accordance with the deep copy principle, where arrayaddr should be the first address of a new contiguous space allocated for the preservation of the data;
(2) MyArray ( int *a, int n), to copy the values in an array of a to the space pointed to by the newly assigned arrayaddr;
(3) Getmax () The strategy that the function takes is to return Max directly (so that the work of Max is computed, done by the constructor)
