Which expression dynamically allocates an array of 10 integers in C++?

Options

A. new int[10]

Answer: (A) new int[10]

The expression new int[10] dynamically allocates storage for an array of 10 integers.

For example:

int *p = new int[10];

Here, p points to the first element of the dynamically allocated array.

The important difference is that new int[10] creates an array, whereas new int(10) creates a single integer initialized with the value 10.
