arrays - What is meant by the statement new employee *[num] in C++ -

i came across statement in book.

new employee *[num];

where employee has been declared struct employee , num int;

this on right hand side of = operator on statement.

so, meant statment? book doesn't offer explanation of said statement.

this allocate memory required hold num number of pointers employee on free store.

e.g:

employee** = new employee* [2]; // 2 pointers on heap

heap:

address (e.g. 0x97a0008): pointer1 employee address + 1 ( 0x97a000c): pointer2 employee

side note: utilize delete[] on arrays can delete above delete[] a but have loop first through entries if have allocated memory them have freed before loose pointer.
