Using Namespace Int: Include Include

The document contains C++ code that defines a class hierarchy for shapes, including a base class 'Shape' and derived classes 'Rectangle' and 'Triangle'. It includes methods to calculate the area for each shape and demonstrates their usage in the main function. However, there are several syntax errors and inconsistencies in the code that need to be corrected for it to compile successfully.
