2. Pointers Arrays: allocation Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array (your return value should be int *). Here is your function prototype (also called function declaration): int * arrayAllocation(int nb); In the main function, ask the user how much memory they want to allocate, i.e ask the user they for how many integers. Call the function with the users answer. Remember the return value in a pointer of integer called ptrArray.
