Differences between exceptions and assertions

Exceptions	Assertions
An exception tells the user of the program that something in the program went wrong.	An assertion documents a program. When it fails, it informs that the program has a bug.
Exceptions are created to deal with problems that might occur in the program.	Assertions are written to state the concepts of a program.
Exceptions are used to test input/output as well as whether parameters are legal or not.	Assertions are documentations that can be checked by running the program.
