Write a C++ program that computes student grades for an assignment as a percentage given each student's score and the total points. The final score should be rounded up tothe nearest whole value using the ceil function in the <cmath> header file. You should also display the floating-point result up to 5 decimal places. The input to the program must come from a file containing multiple lines wih the student's last name, score, and total seperated by a space. In addition, you should print to the console "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 60. Here is an example of what the input file might look:
Weems 50 60
Dale 51 60
Richards 57 60
Smith 36 60
Tomlin 44 60
Bird 45 60
Make sure you design your program in such a way that it prompts the user for the pathname leading to the file containing the data. You may use any methods you learned in class to handle the input file. Be sure to use proper formatting and appropriate comments in your code. The following shows a sample result of running the program using the data shown above. Your program should display output (on the screen) similar to it. (1) The number of students in the input file is unknown. You should use a while loop to detect End Of File. (2) Arrays are not allowed to solve the problem.
Enter the input file name:Â c:/grades.dat
Weems 83% .83333 Well Done
Dale 85% .85000 Well Done
Richards 95% .95000 Excellent
Smith 60% .60000 Need Improvement
Tomlin 73% .73333 Good
Bird 75% .75000 Good
