Write a C++ program that reads data from an input file, takes the data and computes student grades for an assignment by converting the raw score to a percentage given each student's score and the total points. The final score must be rounded up to the nearest whole value using the ceil function in the header file and displayed as a percentage. You must also display the floating-point result up to 5 decimal places. You must use at least 2 functions: one to print the last name of the student and another function to compute and print the percentage as well as "Excellent" if the grade is greater than 90, "Well Done" if the grade is greater than 80, "Good" if the grade is greater than 70, "Need Improvement" if the grade is greater than or equal to 60, and "Fail" if the grade is less than 50. The main function is responsible for reading the input file and passing the appropriate arguments to your functions.
