Write a program that will find the class average of fifteen (15) test scores for five (5) different tests. The class average must be stored into an integer array. You are to have three separate arrays: Note: _jd represents the initials of the programmer. Your array and function names should be named by replace the initials jd with your first and last initials Arrays Student Names Scores Averages Name of array students_jd scores_jd averages_jd Size of array [15][10] [15][5] .[5] Data for array Initialized in code Read from data file Calculated and stored Excluding the main function, your program should have three additional functions that will get the scores, calculate the averages and display your output. Functions Read Input File Calculate Average Output Results Name of function get_jd calc_jd prt_jd Properties of function Called from main Called from main Called from main Definition of Function Should pass scores array and add data to array Should pass average array and add averages to array Should pass students, scores and average array and print data Data file should be named da

An amateur meteorologist wants to keep track of weather conditions during the past year's three -month summer season and has designated each day as either rainy ('R'), cloudy ('C'), or sunny ('S'). Write a modu lar program that stores this information in a 3 x 30 array of characters, where the row indicates the month (0 = June, 1 = July, 2 = August) and the column indicates the day of the month. Note that data is not being collected for the 31st of any month . The program should begin by calling a function to read the weather data in from a file. Then it should create a report that displays for each month and for the whole three-month period, how many days were rainy, how many were cloudy, and how many were sunny. To help it do this, it should use a value -returning function that is passed the array, the number of the month to examine, and the character to look for ('R', 'C', or 'S') . This function shou ld return the number of days the indicated month had the requested weather. Data for the program can be found in the Rai nOrShi ne. da t file located in the Chapter 8 programs folder on this book's companion website. please do this program in c++ and please add comments.
