Summary
Jason, Samantha, Ravi, Sheila, and Ankit are preparing for an upcoming marathon. Each day of the week, they run a certain number of miles and write them into a notebook. At the end of the week, they would like to know the number of miles run each day and average miles run each day.
Instructions
Write a
a function to read and store the runners’ names and the numbers of miles run each day;
a function to calculate the average number of miles run each day;
and a function to output the results. (You may assume that the input data is stored in a file and each line of data is in the following form: runnerName milesDay1 milesDay2 milesDay3 milesDay4 milesDay5 milesDay6 milesDay7.)

- Jason, Sam, Beth, James, and Larry are preparing for an upcoming marathon. Each day of the week, they run acertain number of miles and write them into a notebook. At the end of the week, they would like to know thenumber of miles run each day, the total miles for the week, and average miles run each day. Write a program tohelp them analyze their data. Your program must contain parallel arrays: an array to store the names of therunners and a two-dimensional array of five rows and seven columns to store the number of miles run by eachrunner each day. Furthermore, your program must contain at least the following functions:a. A function to read and store the runner’s names and the numbers of miles run each day;b. A function to find the total miles run by each runner and the average number of miles run each day;c. A function to output the results.

N is an integer (whole number) entered by the user and will indicate to the function how many random dates the user requires. The dates array will be structured as follows: • The array shall have two columns; column 1 will contain numbers indicating the day of each month (1-31) and column 2 will contain numbers indicating the month (Jan 1, Feb=2, Mar = 3.... Dec = 12). . Each day must be randomly generated (using the randi() function) taking into account the maximum number of days in each month (i.e. Jan, Mar, May, Jul, Aug. Oct and Dec have 31 days, Apr. Jun, Sep and Nov have 30 days and Feb will have 28 days). You must use an if-elseif-else statement to decide this. • We are assuming no leap years (e. February can only have days between 1-28). For example, the output from calling the function: output = dategen (3) could…arrow_forward
- In C write a grading program as follows.- Ask the user for the number of students and store it in an integer variable.- Create an array of floats with four rows and columns equal to the number of students storedearlier.- Initialize the array to zeros.Create a menu with the following options (use a do-while loop and repeatedly display the menu):A or a to add student info one student at a timeT or t to display class average for homeworkS or s to display class average for quizzesB or b to display class average for examsZ or z to exit program (program repeats until this exit command is entered)arrow_forwardJAVA PROGRAM: Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.arrow_forwardI wrote this code in c programming. what this code should do is ask how many times its going to run and run that many times(this works), ask how many books there are in a place(this works), then ask the max number of pages you want to read(this works), then asks how many pages there are in a book and put that into an array(works), then sorts the array of pages(works), and then adds the number in the array until you cant which is less than or equal to the max number of pages you want to read, and puts how many books you read(does not work), and then prints out how many books you read. a sample input is 35 206 12 3 10 25 2112 3 6 10 210 319 6 6 3 8 2 12 15 13 7 sample out put should be 345 #include <stdio.h> #include <stdlib.h> void MergeSort(int values[], int start, int end); void Merge(int values[], int start, int middle, int end); void add(int pages[], int count[], long long maxPages, long long total); void Print_Array(int count[], int cases); int main(void) {…arrow_forward
