Problem 1: Strawkcab (6 points)

Write a function Reverse that reverses the elements of its array
parameter a.  For example:

before: 10 20 30 40 50 60 70

after : 70 60 50 40 30 20 10

For maximal credit you may NOT define another !Vector! variable in
the function Reverse.

   void Reverse(Vector<int> & a, int numElts)
   // precondition: a represents: a0,a1, ..., a(numElts-1)
   // postcondition: a represnts: a(numElts - 1), ..., a1,a0




Problem 2: Modal: (6 points)

Test scores in the range 0..100 (including 0 and 100) are stored in a
file, one-per-line:

90
87
23
0
15
...


Write a program that reads all the scores in a file specified by the
user and prints both the average score and the modal score.  The
modal score is the score that occurs most often of all the scores.  
If there are several scores that ``tie'' for modal score then all such
scores should be printed, i.e., if scores of 95 and 98
occur 25 times and all other scores occur fewer than 25 times,
then 95 and 98 should be printed.

#include <iostream.h>
#include <fstream.h>
#include "CPstring.h"
#include <stdlib.h>          // for exit
#include "vector.h"

main()
{
    int num;
    String filename;
    cout << "enter name of file: "
    cin >> filename;

    ifstream input(filename);
    if (! input){
        cout << "could not open " << filename << endl;
        exit(1);
    }




    while (input >> num)
    {








    }

}


(For extra credit, determine the median score.  The median is the
 score ``in the middle'', i.e., half the scores are greater and half are
 smaller.  You can assume that the number of different scores is an odd
 number for this problem if you want to.)
