HOW to use Aspos.cell C++ for add data in Excel?

Trying to check the operation of Aspose.Cells_for_C ++ _ 18.8.
I try to use an example that writes data to an Excel file, BUT:

worksheet-> GetICells () -> GetObjectByIndex (new String (“A1”)) -> PutValue (“Hello World”);

It works incorrectly! For the place of the cell A1 “Hello World”, is recorded - True.

Please modify the line of code as follows and provide your feedback:
worksheet->GetICells()->GetObjectByIndex(new String("A1"))->PutValue((StringPtr)new String("Hello World"));
