Thanks

Hi @MuzammilKhan6 ,

Here you're writing a contract that needs information from another already deployed contract (priceFeed).
This priceFeed, being another contract, has a number of functions defined inside. They are all defined in its interface AggregatorV3Interface.

The line AggregatorV3Interface priceFeed = AggregatorV3Interface(...) means that we want the variable priceFeed to point to a contract that has the structure defined in the AggregatorV3Interface, and which is deployed in the given address (0x8A7...).

We then call the latestRoundData() function of this external contract. It returns 5 variables of which only the second interests us : int256 price.

Does that make sense ?
