Write a program to analyze studentâs scores. each studentâs id and 4 original test scores are saved in the attached file âstudent_id_scores.txtâ. assume there are exactly 15 students in the class.⢠the program first opens the file, reads studentâs ids and scores from the file and saves them in two arrays: o create a one-dimensional string array âidsâ to store the studentâs ids.o create a (parallel) two-dimensional int array âscoresâ to store studentâs original test scores. this array has 5 columns, the original 4 test scores should be saved in the first 4 columns, and the last column will be used to save the average score after the calculation in next step.⢠the program then retrieves test scores from the array âscoresâ, calculates average score and determines the final letter grade based on the rules in the table below for each student. assume average score is integer value.average score = (score1 + score2 + score3 + score4) / 4average score letter grade90 ~ 100 a80 ~ 89 b70 ~ 79 c60 ~ 70 d0 ~ 60 f⢠the average score should be saved back in the 5th column of âscoresâ array.⢠create a new parallel one-dimensional char array âgradesâ to save each studentâs letter grade.⢠program also needs to find the number of a, number of b, number of c, number of d and number of f grade. as well as the highest, lowest and average score of the class.⢠finally, program will display all of the original scores and all results on the computer screen using the format shown as the sample output below.⢠the program must contain at least the following functions: (1) a function âgetscoresâ to read and store data into âidsâ and âscoresâ arrays.(2) a function âanalyzescoresâ to calculate studentâs average score, determine letter grade, get the number of a, b, c, d and f, find the highest, lowest and average score of the class.(3) a function âdisplayresultsâ to display all of the results
