Write a program in c$++$that will read a set of numbers from a file into an array

The array must be dynamic

The size is only as big as the number of values in the file

The program must calculate the size of the array. Do not hard code a value

All interaction with the array must be done via a pointer.

No bracket notation

Use pointer arithmetic to traverse the arrays

Search the array to find the following items:

The lowest number in the array

The highest number in the array

The sum of the numbers in the array

The average of the numbers in the array
