Exceptions: Exceptions in Constructors

Note

The Microsoft Foundation Classes (MFC) library continues to be supported. However, we're no longer adding features or updating the documentation.

When throwing an exception in a constructor, clean up whatever objects and memory allocations you have made prior to throwing the exception, as explained in Exceptions: Throwing Exceptions from Your Own Functions.

When throwing an exception in a constructor, the memory for the object itself has already been allocated by the time the constructor is called. So, the compiler will automatically deallocate the memory occupied by the object after the exception is thrown.

For more information, see Exceptions: Freeing Objects in Exceptions.
