Create **Car** and **CarOwner** structures. 4 | The first one should includes the following properties: 5 | ``` 6 | 1) price 7 | 2) manufacturer 8 | 3) configOfModel as mapping (model => number of config) 9 | 4) petrolConsumptionPerMile 10 | 5) signature 11 | 6) presence 12 | ``` 13 | The second one should contains the following properties: 14 | ``` 15 | 1) addr 16 | 2) discount 17 | 3) carIDs 18 | ``` 19 | 2. Create next variables: 20 | ``` 21 | 1) carDealer 22 | 2) carID (this variable should starts from 1) 23 | 3) carOwnerID (this variable should starts from 1) 24 | 4) cars mapping (carID => car) 25 | 5) carOwners mapping (carOwnerID => car owner) 26 | 6) carOwner mapping (owner's address => carOwnerID) 27 | ``` 28 | **Prompt:** `carIDs` property in `CarOwner` structure should stores only `MAX_CARS_PER_PERSON` unique identifiers. 29 | ### Task 2: Library 30 | Add `SafeMath` library to `CarMarket` contract. 31 | ### Task 3: Setter function 32 | Create function which will creates new Car object. Call it as `addCar`. 33 | 1. Get `c` variable type `Car` declared as a storage pointer. 34 | 2. Add all properties to `Car` object. 35 | 3. Increment `carID` variable. 36 | ### Task 4: Modifier. Require statement. 37 | Create `onlyCarDealer` modifier that will allows to give access only for `carDealer`. 38 | Add this modifier to `addCar` function. 39 | ### Task 5: Payable function. Msg.sender, msg.value. Conditional statements. Loop. Transfer method. 40 | Create `payable` function called `buyCar` with one parameter called `_carID`. This function will accept ETH from buyers. 41 | 42 | First, we prepare the variables for our function: 43 | 1. Let's say that `carID == 0` is a empty index that doesn't contain any car. It will come in handy in the future to get buyer's cars. Create variable `NULL_CAR` with zero value. 44 | 2. Create `NOT_CAR_OWNER` variable with zero value. 45 | And `CAR_OWNER` variable with value `1`. 46 | Create mapping `isCarOwner` there person address => person state. 47 | If person has never bought any car his person state will be NOT_CAR_OWNER, else - CAR_OWNER. 48 | 3. Create `DECIMAL_MULTIPLIER` variable with value `1e18`. This variable will need us for calculating later. 49 | 4. Create `IN_STOCK` and `OUT_OF_STOCK` variables with values `true` and `false` respectively. 50 | 51 | Let's start to code our `buyCar` function: 52 | 1. The `carDealer` can't buy a car. 53 | 2. Parameter `_carID` should be less or equal last `carID`. 54 | **Prompt:** `carID` variable contains future car unique identifier. 55 | 3. Parameter `_carID` shouldn't be equals to `NULL_CAR`. 56 | 4. Create car instance by `_carID` unique identifier. 57 | 5. Car should be `IN_STOCK`. 58 | 6. Create local variable called `_carPrice` that will contains the price of selected car. 59 | 7. Let's check: if `msg.sender` buy car at first time. 60 | **Prompt:** remember the `isCarOwner` variable and `NOT_CAR_OWNER` person state. 61 | 62 | 8. Let's start with person who has never bought a car. 63 | a. Check if send ETH >= `_carPrice`. 64 | b. Create local variable `_newCarOwnerID` with value `carOwnerID`. 65 | c. Now person has bought a car. Set CAR_OWNER state. 66 | d. Create `_newCarOwner` instance of `CarOwner` object with `_newCarOwnerID` unique identifier. 67 | e. Set `carOwner` properties `addr` and `carIDs`. **Prompt:** `carIDs` should be array with one element. 68 | f. Add buyer to `carOwner` variable. 69 | g. Increment `carOwnerID`. 70 | What about person who has already bought a car: 71 | a. Create `_carOwnerID` local variable with value of `carOwner` unique identifier. 72 | b. Create variable `_carOwner` - instance of `CarOwner` with `_carOwnerID` unique identifier. 73 | c. Check `discount` of buyer. If it's more than zero than calculate new `carPrice` given the discount. **Prompt:** Get `_carPrice` and subtract it from (`_carPrice` multiply by discount and divide by DECIMAL_MULTIPLIER). Discount should equal from `1e16` to `1e18` because solidity doesn't have floating-point numbers. 74 | d. Check if send ETH >= `_carPrice`. 75 | e. Check last item of `_carOwner.carIDs` for `NULL_CAR` value. If it's false than person has already bought `MAX_CARS_PER_PERSON`. 76 | f. Next you should use loop for adding new car ID for `_carOwner`. 77 | 78 | 9. Buyer can send more ETH than is the car worth. You should calculate remain value out of conditional statement like `msg.value` without `_carPrice`. 79 | 10. And if remain value more than zero return remain ETH to car buyer. 80 | 81 | ### Task 6: Getter function 82 | You have to create `getOwnerCars` function that will returns all cars which `carOwner` has already buy. 83 | 84 | ### Task 7: Events 85 | Create: 86 | ```javascript 87 | event AddCar(address carDealer, uint carID); 88 | event NewCarOwner(uint carOnwerID, address carOwnerAddress); 89 | event BuyCar(uint carID, uint carOwnerID); 90 | ``` 91 | And arrange it in the right places. 92 | 93 | ___ 94 | 95 | ### Additional assignment 96 | Create `setCarOwnerDiscount` and `editPresence` functions. 97 | Create Interface `ICarMarket`. 98 | Add here all constant variables modifiers and functions without body. 99 | Inherit `CarMarket` contract from `ICarMarket` interface. 100 | 101 |
