9.2

1. Error: Destructors are not allowed to return values (or even specify a return type) or take arguments.

   Correction: Remove the return type void and the parameter int from the declaration.

2. Error: Constructors are not allowed to return values.

   Correction: Remove the return type int from the declaration.

3. Error: The class definition for Example has two errors. The first occurs in function getIncrementedData. The function is declared const, but it modifies the object.

   Correction: To correct the first error, remove the const keyword from the definition of getIncrementedData. [Note: It would also be appropriate to rename this member function, as get functions are typically const member functions.]

   Error: The second error occurs in function getCount. This function is declared static, so it’s not allowed to access any non-static class member (i.e., data).

   Correction: To correct the second error, remove the output line from the getCount definition.
