Write the following a functions:

• One that accepts an ifstream and a pointer to an int array as arguments. The function should ask the user for the number of elements in said list, create a dynamic array, and store the values from the file into it. The function should return the length of the new array.
• One that accepts a pointer to an int array, and the array's size as arguments. The function should create a copy of the array, except that the elements should be be in reverse order in the copy. The function then returns a pointer to the new array.

Demonstrate both functions in a single program that reads numbers from a file and prints the reversed list on screen. Do not use vectors. Remember that ifstream must be passed by reference.
