Assignment 7 A: What’s your grade? In this class (as well as the lecture class), we calculate grades using a process called “weighted averages”. The formula works by averaging all the games in a particular category, then multiplying the result by a percentage (the “weight”). All categories are then added up to give you your final grade. In our class, that would look like this: Final Grade = (average(Labs) * 0.10) + (average(Assignments) * 0.40) + (average(Midterm) * 0.20) + (average(Final) * 0.30) For this assignment, you will build a program that can calculate your grade in CSE 1321L using the formula above. Your main method will ask users to input the following information: • 13 individual lab grades (since the lowest is dropped per FYE policy) • 8 assignment grades • 1 midterm grade • 1 final exam grade You will then create and use two methods outside of main to calculate your grade: • A method to calculate the average value of a category. The method should take in an array of floats and the integer size of the array, and return a float value for the average of the category. • A method to calculate the weighted points of a category. The method should take in the returned value from the previous method and a float value for the category’s percentage (e.g. 0.4f) and return a float value for the weighted points of the category. You will call the same methods for each of the four grade categories – the functions should be flexible enough to work for any values. Once you have all four calculated, add them up and print the results.
