Operation on array:

void Array::add( Object& toAdd )

{

lastElementIndex++;

while( ptrAt( lastElementIndex ) != ZERO &&

lastElementIndex <= upperbound

)

lastElementIndex++;

if( lastElementIndex > upperbound )

reallocate( lastElementIndex - lowerbound + 1 );

setData( lastElementIndex, &toAdd );

itemsInContainer++;

CHECK( itemsInContainer > 0 );

}

void Array::addAt( Object& toAdd, int atIndex )

{

PRECONDITION( atIndex >= lowerbound );

if( atIndex > upperbound )

reallocate( atIndex - lowerbound + 1 );

if( ptrAt( atIndex ) != ZERO )

{

delete ptrAt( atIndex );
