hey guys, i have a problem with this program...

void findMax(int arr[], int n, int* pToMax)
    {
        if (n <= 0) 
            return;      // no items, no maximum!
    
	int max = arr[0];
	pToMax = &arr[0];
	
	for (int i = 1; i < n; i++)
	{
	    if (arr[i] > max)
	    {
	         max = arr[i];
	         pToMax = (arr+i);
	    }
	}
    }       
	
    int main()
    {
        int nums[4] = { 5, 3, 15, 6 };
        int *ptr;

        findMax(nums, 4, ptr);
        cout << "The maximum is at address " << ptr << endl;
        cout << "It's at index " << ptr - nums << endl;
        cout << "Its value is " << *ptr << endl;
    }

i know that the problem is that the compiler is outputting the memory address and not the actual value that i want it to output. how would i change that?
thanks guys

If you want findMax() to change the value of ptr in main() then you have to pass the parameter by reference and not by value.

void findMax(int arr[], int n, int** pToMax)
 {
    ...
    *pToMax = &arr[0];

}

int main()
{
...
    findMax(nums, 4, &ptr);
}

Or since this is c++

void findMax(int arr[], int n, int*& pToMax)
 {
    ...
    pToMax = &arr[0];

}

int main()
{
...
    findMax(nums, 4, ptr);
}
