First, create a step-by-step algorithm (or a graphical flowchart) to determine and display a students letter grade in a course. A course grade is typically reported as a real number with values from 0 to 100. Your algorithm should ask the user to provide a grade in numerical form and display the letter grade corresponding to the numerical grade if the entered value is between 0 and 100 inclusive. If the value is outside of this range, ask the user to re-run the program and enter a value within the range of 0-100. Typical ranges for grades are given below: A: 90 grade B: 80 grade < 90 C: 70 grade < 80 D: 60 grade < 70 F: grade < 60 Then, write a MATLAB script that implements your algorithm/flowchart. The program should ask the user for his or her numeric grade and the letter grade should be generated as the output. Specifically, the computer must display the following message: You entered a score of . Your letter grade is . At the location given by , the program must display the numerical grade that the user just entered, and at the location given by , the program must display the letter grade that it calculated based on the users input. Therefore, if the user entered a score of 74, the message must show: You earned a score of 74. Your letter grade is B. Similarly, if the user entered a grade of 56, the message must show: You earned a grade of 56. Your letter grade is F.
