1. 30 points Write a C++ program that computes student grades for an assignment as a percentage given each students score and the total points. The final score should be rounded up to the nearest whole value using the celi function in the $$ header file. You should also display the floating-point result up to 5 decimal places. You should have a function 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 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

-

The output of your program should look like:

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
