# BLCK_CHN_Eng

## Sol Basic:

### In each file there will be examples of specific use of Solidity language:

###

### A) MyRun.sol: 

### You can create a list of runs you do specifying name of the run and related distance in Km. It is a simple example of:

### - Contract{}

### - struct Name{typeVarN VarN;...}

### - ArrayName[] public name;

### - function functionName(typeVarN _varN, ... ) public {}

### - mapping(type1 => type2) public name;

### The file can be run in Remix or VSC

### //

### B) ChainlinkETHUSD.sol: 

### Retrieve ETH/USD last price using ChainLink interface. It is an exeample to:

### - Use an interface via:

#### -- import "@chainlink/contracts..."

#### -- import "./fileInSameFolder"

### - Call Call interface functions: 

#### -– version(): returns interface version

#### -– latestRoundData(): returns non decimal price, last update timestamp >> example of multivariable function

### You can run it in Remix, but if you run it using vsc you need to twick it a bit - it is explained in the comments

### //

### C) AggregatorV3Interface.sol:

### Interface code from npm Chainlink, copied from: 

### https://github.com/smartcontractkit/chainlink/blob/develop/contracts/src/v0.6/interfaces/AggregatorV3Interface.sol

### It is needed if you want to import the interface file directly from your directory
