CSC135 Program #7-Arrays2D (student averages) You are to modify the program that you wrote for Program #6 (Arrays) to make use of 2D (two dimensional) arrays. Refer to that assignment for details not specified here First, name your program: arrays.cpp you can copy it from the old program as follows cp arrays.cpp arrays2D.cpp In the previous program, you read student data from a file called studentScores.dat. You loaded the information into three parallel arrays, computing the average and letter grades for each student. You will do the same for this assignment, however, ALL of the data must be stored in parallel arrays first, two of which will be 2-dimensional, BEFORE any computation may be ne Specifically, you should read the student id number (SID) as before into an array. The tests and programs scores should be loaded into two separate 2D arrays. The 2D array containing the test information will have 3 columns for each student's 3 test scores. Similarly, the 2D array for the program scores will have 6 columns for the 6 program scores. All of this should be done in one function Once the data have been loaded into the 3 parallel arrays, you can proceed to determine the average and the letter grade for each student and store them in parallel arrays, as was done in the previous assignment. Finally, complete the assignment, as before, by generating the numbers of each grade (A, B, C, D, F), and the overall class average as described in the prior assignment
