Question

Create a small program that calculates the final grade in this course, given the different assignments and exams you will be required to take. The program should ask for all the grades through the semester, and as a final output it should compute the weighted average as well as give the final letter grade. You should use the syllabus for this course to calculate the final grade. • Five assignments worth 30 points each. • Three projects worth 100 points each. • Seven quizzes worth 20 points each. • Participation is worth 10 points. Your final grade is calculated out of the total points you earn. For example, if the total possible points are 500 and you have a 461, your grade is 461/500 x 100 = 92% which is an A-. Extra Credit: If you wish to challenge yourself, you can make sure that the program “fails gracefully”. If someone enters the wrong information or data type, prompt the user with a handled message. Although we will deal with error handling later in the semester, thinking about exceptions is always important. Another way to make the program slightly more challenging is to accept an undetermined number of quizzes.
