error: invalid conversion from 'int' to 'int*'

Hi everyone, on line 76 I get the error of an invalid conversion from and int to *int. Please bear in mind the function prototype for findmax must be the way it is. Can anyone help me? I appreciate it.

Code:

#include <iomanip>
#include <iostream>

using namespace std;

#define MAX 100

bool isAscending (int *a, int len);
bool isDescending (int *a, int len);
bool isInOrder (int *a, int len);
double avg (const int *x, int len);
int *findmax (const int *x, int n);
int getInfo (int *a, int max);
int total (const int *a, int len);
void sort (int *x, int n);
void swap (int &x, int &y);

int main()
{
    int a[MAX];
    int i = 0;
    int len;
    len = getInfo (a, MAX);
    double x = avg (a, len);

    if (len > 0) cout << "Avg: " << x << endl;
    for (;i < len; i++) cout << setw(4) << *(a+i);
    cout << endl;

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

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

    for (i = 0; i < len; i++) cout << setw(4) << *(a+i);
    cout << endl;

    return 0;
}

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

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

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

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


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

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

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

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

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

Oh sorry! Line 76 is;

Code:

return temp;

You are supposed to return an integer pointer, not an int. According to my understanding of the meaning of this function, just return (x+temp).

I do not think that is it. It gives me the same error only now it says "const int* to int*" for the same line. The prototype for the function must be intact. If I remove the * in the function prototype the program works perfectly but unfortunately I have to use the *.

x+temp is correct except that it will also require a const_cast to remove the constness.

The method signature is a bit dubious though, due to the const in only one of the two places.

Thanks everyone! It is now working!
