i guess u have not initialized [B]iRowCount[/B] and [B]iNoOfCol[/B]. Also note that [B]iRowCount<=MAX_ROW and iNoOfCol<=MAX_COL[/B]. Otherwise u will get array outofbound error (or seg fault)

Below is an idea that u can apply. It is not the complete implementation. U can use this approach may be with some minute modification.
