how do i convert the min_max function to the method of the IntArray class?
class IntArray
{private :
int a[];
int n;
..........
};
void min_max(int n,int a[],int&mini,int &maxi)

{
mini=a[0];
maxi=a[0];
for (int i=1; i<n; i++)
{
if (mini>a[i])
mini=a[i];
if (maxi<a[i])
maxi=a[i];

}

}

class IntArray
{
private:
    int a[];
    int n;
public:
    void min_max(int &mini, int &maxi)
    {
        mini = a[0];
        maxi = a[0];
        for (int i = 1; i < n; i++)
        {
            if (mini > a[i])
                mini = a[i];
            if (maxi < a[i])
                maxi = a[i];
        }
    }
};

But see my suggestion in the other thread to return the index in mini and maxi instead of the value.

Note that I don't pass n or a to the method. The method will use the n and a members of the class.

Error : no matching function for call to 'IntArray::min_max()'|
why?
