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.
