Thread: array query

I'm writing this program right now where the user inputs integers with a limit of 100 integers and entering -999 to denote the end of the list. I'm having some trouble... it seems like the way that I have it written now, the program must read 100 integers no matter what. But I don't know what to change. I tried flipping around my "while" and "for" statements, but then that gave me some kind of internet explorer error and shut down. Anyways, if anyone can take a look and see what I have going wrong here, let me know. I'd really appreciate it.

Code:

#include <iostream>
#include <iomanip>

using namespace std;

const int sentinel = -999;
void selectionSort(int number[], int length);

int main()
{
	int number[100];
	int index;

	cout << "Enter a maximum of 100 positive integers ending with " << sentinel << endl;
	
	for (index = 0; index < 100; index++) 
	{
		while (number[index] != sentinel)
		{
			cin >> number[index];
		}
	}

	selectionSort(number, 100);
	
	for (index = 0; index < 100; index++)
		cout << number[index] << endl;


	return 0;
}

void selectionSort(int number[], int length)
{
	int index;
	int smallestIndex;
	int minIndex;
	int temp;

	for (index = 0; index < length - 1; index++)
	{
		smallestIndex = index;
		for (minIndex = index + 1; minIndex < length; minIndex++)
			if (number[minIndex] < number[smallestIndex])
				smallestIndex = minIndex;

		temp = number[smallestIndex];
		number[smallestIndex] = number[index];
		number[index] = temp;
	}
}
