C++ : Write a program that opens a file that contains random numbers and reads all the numbers from the file, and calculate/determine the following:

Counts how many numbers were read from the file

The sum of all the numbers in the file (a running total)

The average of all the numbers in the file

Determine the lowest and highest values in the file

The program must validate that the file was opened before reading from the file.

If file does not exist then display a message telling the user that the file could not be opened and exit the program.
