CString myStr[4]={_T("One"), _T("Two"), _T("Three"), _T("Four")};

myMap.InitHashTable(257);

// Add 4 elements to the map.
myMap.SetAt(myStr[0], _T("Odd"));
myMap.SetAt(myStr[1], _T("Even"));
myMap.SetAt(myStr[2], _T("Odd"));
myMap.SetAt(myStr[3], _T("Even"));

// Print the element values with odd key values.
CMapStringToString::CPair *pCurVal;

for (int i = 0; i < 4 ; i += 2)
{
   pCurVal = myMap.PLookup(myStr[i]);
      _tprintf_s(_T("Current key value at %s: %s\n"), 
   pCurVal->key, pCurVal->value);
}
