Explain how memory is allocated and deallocated in C$++.$ Additionally, write a block of code that makes a copy of the following array using dynamic memory. Also demonstrate how the newly allocated array must be deallocated when it is no longer needed in the program.

const int SIZE $=10$;

double values$[$SIZE$]=\backslash \{45,90\mathrm{.}2,20\mathrm{.}3,10\mathrm{.}4,7\mathrm{.}65.495\mathrm{.}34,100\mathrm{.}00,1,66\mathrm{.}5,49\mathrm{.}8\backslash \}$;
