Pointer Array Help

[jkfde]

I need to dynamically allocate the donations array in my code, and ask the user to input the value of the array.
Here is the original code

// This program shows the donations made to the United Cause
// by the employees of CK Graphics, Inc. It displays
// the donations in order from lowest to highest
// and in the original order they were recieved.
#include <iostream>
using namespace std;

// Function prototypes
void arrSelectSort(int *[], int);
void showArray(const int [], int);
void showArrPtr(int *[],int);

int main()
{
	const int NUM_DONATIONS = 15; // number of donations
		
	// An array containing the donation amounts.
	int donations[NUM_DONATIONS] = {5, 100, 5, 25, 10, 5, 25, 5, 5, 100, 10, 15, 10, 5, 10}; 
	int *arrPtr[NUM_DONATIONS]; // an array of pointers to int.

	// each element of arrPtr is a pointer to int. 
	// make each element point to an element in the donation array
	for (int count = 0; count < NUM_DONATIONS; count++)
		arrPtr[count] = &donations[count];

		//sort the elements of the array to pointers
		arrSelectSort(arrPtr, NUM_DONATIONS);

		//Display the donations using the array of pointers. This
		//will display them in sorted order.
		cout << "The donations, sorted in ascending order are: \n";
		showArrPtr(arrPtr, NUM_DONATIONS);

		//display the donations in their original order.
		cout << "The donations, in their original order, are: \n";
		showArray(donations, NUM_DONATIONS);
		return 0;
	}

void arrSelectSort(int *arr[], int size)
{

	int *minElem;

	for (startScan=0; startScan < (size-1); startScan++)
	{
		minIndex = startScan;
		minElem = arr[startScan];
		for (int index = startScan + 1; index < size; index++)
		{
			if (*(arr[index]) < *minElem)
			{
			minElem=arr[index];
			minIndex = index;
			}
		}
	arr[minIndex] = arr[startScan];
	arr[startScan] = minElem;

{

}

Here is my code with changes

// This program shows the donations made to the United Cause

#include <iostream>
#include <iomanip>
using namespace std;

void arrSelectSort(int *[], int);
void showArray(const int [], int);
void showArrPtr(int *[],int);

int main()
{
	int numDon;
	cout << "How many numbers are in the array? " << endl;
	cin >> numDon;
	 

	// An array containing the donation amounts.

	int *donations= new int [numDon];
			for (int i=0;i<numDon;i++)
		{
			cout << "Please enter a number for the " << i+1 << " element of the array";
			cin >> donations[i];
		}
	

	// each element of arrPtr is a pointer to int. 
	// make each element point to an element in the donation array


		//sort the elements of the array to pointers
		arrSelectSort(&donations, numDon);

		//Display the donations using the array of pointers. This
		//will display them in sorted order.
		cout << "The donations, sorted in decending order are: \n";
		showArrPtr(&donations, numDon);

		//display the donations in their original order.
		cout << "The donations, in their original order, are: \n";
		showArray(donations, numDon);
		return 0;
	}

How can i make it pass the array

[Darkmaster]

if you want to pass an array as a parameter of a function use this

void my_function(int my_Array[size]);  //you can also just write my_Array[] without size
void myfunction(int my_Array[size])    //same is the line above
{
blablabla code and stuff
}

int main()
{
   int A[size];
   myfunction(A);
}

It needed to be allocated dynamically. i was having troubles getting a pointer for it. i think i got it figured out now though
