Raptor Grade Calculator

Objective

Use the repetition control structure to write code in Raptor to calculate letter grade for a course for a set of students. DO NOT use the array. A Program that uses arrays for this exercise WILL NOT be accepted.

Process and additional criteria

Ask for the number of students in a course. Make sure the user enters 1 or more students. Must use a loop to validate. For each student,

• Ask the user for the number of assignments given in a course. Make sure the user enters 1 or more assignments. Must use a loop to validate.
• Ask the user for the score on each assignment and calculate the average assignment score. Make sure that the user enters a valid test score (values between 0 and 100).
• Ask the user for grade for 2 exams and the final exam. You don't have to validate the exam scores.
• Calculate the overall grade by: (assignment average * .65) + exam1 * .10 + exam2.1+ Final Exam *.15.
• Calculate and display the final letter grade based on the following table.

A-90-100
B-80-less than 90
C-70- less than 80
D-60- less than 70
F-Less than 60
