Module/Week 5 (USER-DEFINED FUNCTIONS) 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 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. Here is an example of what the input file might look like: Weems 50 60 Dale 51 60 Richards 57 60 Smith 36 60 Tomlin 44 60 Bird 45 60 Here is an example of what the output of your program might look like: Meems 83% .83333 Well Done Dale 85% .85000 ell Done Richards 95% .95000 Excellent Smith 60% .60000 Need Improvement Tomlin 73% .73333 Good Bird 75% .7500?
