a$)$ Describe a situation where dynamic memory allocation using the keyword new, such as:

int$*$ p $=$ new int$[60000]$;

$$ is preferable to using an automatic variable, such as:

$$

$$ int p$[60000]$;

$$

The keyword New is a request for memory to be allocated on the free storage, if there is not enough memory, the NEW will initialize memory and return the new address.
