Answer:
C++ program explained below for the problem
Explanation:
// UpComingMarathon.cpp : Defines the entry point for the console application.
//header files
#include "stdafx.h" //optional
#include <iostream>
#include <cstring>
#include <fstream>
#include <iomanip>
using namespace std;
//declare the gobal array of type double
double average[5];
//declare the function prototypes
void getData(ifstream& inf, string n[], double runData[][8], int count);
void calculateAverage(double runData[][8], int count);
void print(string n[], double runData[][8], int count);
int main()
{

if(inputfile)
{
//call the method getData

}
else
{
//error message
cout<<"Sorry! Unable to open the file."<<endl;
system("pause");
return 0;
}
//close the file
inputfile.close();
//call the method calculateAverage to compute the
//average miliage of each runner
calculateAverage(runningData, 5);
//call display the names and their weekly run rate and their averages
print(names, runningData, 5);

return 0;
}
//definition of method getData that reads the data from the file and
//stores the names into array n and run data into runData array
//simultaneously.
void getData(ifstream& inf, string n[], double runData[][8], int count)
{

}
//definition of method print that prints the output
//in a tabular format
