c++ - What's the difference between new char[10] and new char(10)

Question

In C++, what's the difference between

char *a = new char[10];

and

char *a = new char(10);

Thanks!

Answer 1

The first allocates an array of 10 char's. The second allocates one char initialized to 10.

Or:

The first should be replaced with std::vector<char>, the second should be placed into a smart pointer.
