Question

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 program to help them analyze their data. Your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. Furthermore, your program must contain at least the following functions:

• 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.)

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
