Average function is not averaging...

Hi everyone. I have enclosed my sorting program and for some reason the average function is not averaging. I cannot find my mistake. The program sorts no problem at all but my average takes the smallest integer and uses it as the average. Can anyone take a looksee and tell me where my mistake is? Thanks!

Code:

//list.h
#ifndef LIST_H_INCLUDED
#define LIST_H_INCLUDED

#include <iomanip>
#include <iostream>

using namespace std;

#define MAX 100

bool isAscending (int *array, int len);
bool isDescending (int *array, int len);
bool isInOrder (int *array, int len);
double average (const int *array, int len);
int *findMax (const int *x, int n);
int getInfo (int *array, int max);
int total (const int *array, int len);
void sort (int *x, int n);
void swap (int &x, int &y);

#endif // LIST_H_INCLUDED

//main.cpp
#include "list.h"

int main()
{
    int array[MAX];
    int counter = 0;
    int len;
    len = getInfo (array, MAX);
    double x = average (array, len);

    if (len > 0) cout << "\nAvg: " << x << endl;

    for (;counter < len; counter++) cout << setw(4) << *(array + counter);
    cout << endl;

    if (isInOrder (array, len)) cout << "its in order" << endl;
    else sort (array, len);

    if (isInOrder (array, len)) cout << "its in order" << endl;

    for (counter = 0; counter < len; counter++) cout << setw(4) << *(array + counter);
    cout << endl;

    return 0;
}

//isAscending.cpp
#include "list.h"

bool isAscending (int *array, int len)
{
    for (int counter = 0; counter < len - 1; counter++)
        if (*(array + counter) > *(array + counter + 1)) return false;
    return true;
}

//isDescending.cpp
#include "list.h"

bool isDescending (int *array, int len)
{
    for (int counter = 0; counter < len - 1; counter++)
        if (*(array + counter) < *(array + counter +1)) return false;
    return true;
}

//isInOrder.cpp
#include "list.h"

bool isInOrder (int *array, int len)
{
    return isAscending (array, len) || isDescending (array, len);
}

//average.cpp
#include "list.h"

double average (const int *array, int len)
{
    int tot = total (array, len);
    return (double) tot/len;
}

//findMax.cpp
#include "list.h"

int *findMax (const int * x, int n)
{
    int temp = 0;
    int counter = 1;
    while (counter <= n)
    {
        if (*(x + counter) > *(x + temp)) temp = counter;
        counter++;
    }
    return (const_cast < int *> (x + temp));
}

//getInfo.cpp
#include "list.h"

int getInfo(int *array, int max)
{
    int counter = 0;
    while (cin >> *array)
    {
        array++;
        counter++;
        if (counter == max) break;
    }
    return counter;
}

//total.cpp
#include "list.h"

int total (const int *array, int len)
{
    int sum = 0;
    while (len--) sum +=*array;
    return sum;
}

//sort.cpp
#include "list.h"

void sort (int *x, int n)
{
    int *j;
    while (n--)
    {
        j = findMax (x, n);
        swap (*j, *(x + n));
    }
}

//swap.cpp
#include "list.h"

void swap(int &x,int &y)
{
    int temp = x;
    x = y;
    y = temp;
}

Your total function is wrong. It keeps summing the first element in the array only.
Also consider using std::vector instead and use array[n] instead of *(array + n).
And naturally, use a reference for the vector (or iterators) instead of pointers.

Thanks Elysia! We have not gotten to OOP yet even though it is an OOP class. As for the pointer to arrays, this is the way the professor wants it right now. I appreciate your input very much!

Alright then. But you could at least remember it for future reference. It should be helpful!

I will do! Thanks!
