The +main idea is that you can have preconditions and postconditions that +describe the functionality of your program. These are then proven +automatically by dafny, which uses the implementation to try and prove +the postcondition assuming that the precondition holds. + +This cannot always be the case though, and one can therefore help the +theorem prover by adding assertions in different places. |
