Could someone please help me with this assignment?
Exercise 1: Complete this program as directed.
Exercise 2: run the program with the following data: 90 45 73 62 -99
and record the output.
Exercise 3: Modify your program from Exercise 1 so that it reads the information from the
gradfile.txt file, reading until the end of file is encountered. You will need to first
retrieve this file and place it in the same folder as your C++ source code. Run the
program.

// This program will read in a group of test scores( positive integers from 1 to 100)
