#include "derived.h"
#include "multithread.h"
#include <iostream>



int main()
{
    using namespace std;
    const int nSize = 26;
    int loop;


    // Create threadable objects


    Derived ObjectArray[nSize];
    for (loop = 0; loop < nSize; ++loop)
    {
        // letters of the alphabet
        ObjectArray[loop].SetChar('a' + (loop % 26) );
    }


    // Create threads


    MultiThread ThreadArray[nSize];

        ThreadArray[loop].WaitUntilDone();
