c++ remove duplicates from array

[dragonk2]

ok... i'm trying to remove same value that is entered something like this

Enter a non-negative integer (negative to quit): 1
Enter a non-negative integer (negative to quit): 2
Enter a non-negative integer (negative to quit): 3
Enter a non-negative integer (negative to quit): 2
Enter a non-negative integer (negative to quit): 1
Enter a non-negative integer (negative to quit): 6
Enter a non-negative integer (negative to quit): 3
Enter a non-negative integer (negative to quit): 4
Enter a non-negative integer (negative to quit): 5
Enter a non-negative integer (negative to quit): 2
Enter a non-negative integer (negative to quit): -4
You entered:
1 2 3 6 4 5

here is my code

#include <iostream>
using namespace std;

const int ARRAY_SIZE = 1000;

void printList(const int list[],
	int numItems);
int indexOfSmallest(const int list[], int startingIndex, int numItems);
void sort(int list[], int numItems);
void readNumbers(int list[], int &numItems);
  // bool checkSameNumber(int list[], int list2[], int numItems);

int main()
{
	int list[ARRAY_SIZE];
	int numItems;


	readNumbers(list, numItems);
	sort(list, numItems);
	cout << "The sorted list: "
		<< endl;
	printList(list, numItems);

	system("pause");
	return 0;
}



void readNumbers(int list[], int &numItems)
{
	int number;
	int count = 0; // the number of numbers that have been entered

	cout << "Enter a number (negative number to quit): ";
	cin >> number;
	while (number >= 0 && count < ARRAY_SIZE) {
		list[count] = number;
		count++;
		if (count < ARRAY_SIZE) {
			cout << "Enter a number (negative number to quit): ";
			cin >> number;
		}
		else {
			cout << "The array is now full." << endl;
		}
	}
	numItems = count;
}


void sort(int list[], int numItems)
{
	for (int count = 0; count < numItems - 1; count++) {
		swap(list[indexOfSmallest(list, count, numItems)],
			list[count]);
	}

}


int indexOfSmallest(const int list[], int startingIndex, int numItems)
{
	int targetIndex = startingIndex;

	for (int count = startingIndex + 1; count < numItems; count++) {
		if (list[count] < list[targetIndex]) {
			targetIndex = count;
		}
	}

	return targetIndex;
}

void printList(const int list[],
	int numItems)

{
	int i = 0, k = 0;
	while (i < numItems) {
		if (list[i] == list[i + 1])
			i++;
		else {
			list[k] = list[i]; // at here ERROR displaced not quit sure why....
			k++; i++;
		}
	}
	for (int j=0; j<k; j++){
		cout << list[j] << " ";
	}
}

all the things are working fine but i am struggling with void printList(const int list[],
int numItems)
i tried set the two array and remove when it's same but it seems not working... any solution?

The printList function takes the array as a const, but then you try to change the array on line 85. Remove the const keyword from the parameter list as well as in the prototype and it should work fine.
