unresolved external

Simple enough. Been doing exercises for days to brush up for next term and this one (selectionSort func followed by sequentialSearch) keeps giving me error:
Unresolved External...???

Code:

#include <iostream>

using namespace std;

const int A_S = 10;

int seqSearch(const int list[], int listLength, int searchItem);
void selectionSort (int list[], int length);

int main()
{
	int list[] = {2, 56, 34, 25, 73, 46, 89, 10, 5, 16};
	int i;
	int index;
	int number;

	selectionSort(list, 10);
	cout << "After sorting, the list elements are:" << endl;
	for (i = 0; i < 10; i++)
		cout << list[i] << " ";
	cout << "Enter the number to be searched: ";
	cin >> number;
	cout << endl;

	index = seqSearch(list, A_S, number);

	if (index != -1)
		cout << number << " is found at position " << index << "." << endl;
	else
		cout << number << " is not in the list." << endl;

	return 0;
}

void selctionSort (int list[], 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 (list[minIndex] < list[smallestIndex])
				smallestIndex = minIndex;

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

int seqSearch(const int list[], int listLength, int searchItem)
{
	int loc;

	bool found = false;

	for (loc = 0; loc < listLength; loc++)
		if (list[loc] == searchItem)
		{
			found = true;
			break;
		}

		if (found)
			return loc;
		else
			return -1;
}

Code:

list[index] = temp;
//Here what is the value of temp?

(facepalm) got it...simple typo
...Thank you 777.

Don't mention.....
These mistakes are common ...... Not your mistake... Every programmer does the same :-)

You should seek to use vectors or iterators instead of pure arrays. They make your code dangerous.
