## Register With Events
|
|
|
|
|
|
|
|
|
|
In order to facilitate the use of your Smart Contract, you will add events.
|
|
|
|
|
|
|
|
|
|
Events in solidity are used to facilitate the retrieval of information.

### Instructions
|
|
|
|
|
|
|
|
|
|
Write solidity smart contract `RegisterWithEvents` that provides:
|
|
|
|
|
|
|
|
|
|
- The functions `addDocument()` and `getDate()` as specified in the prior exercise.
|
|
|
|
|
- An event `event DocumentAdded(bytes32, uint)` that triggers when a new document is added to the register
|
|
|
|
|
|
|
|
|
|
As in prior exercises, the file must be named register-with-events.sol while the contract is named RegisterWithEvents.
