Lesson 1, 2 & 3

[arsalmalik786]

Hi everyone, I have completed 32 hours Full-Blockchain-Solidity-course-js and now practice from zero, basically, I'm already working with solidity and blockchain but now I start again to polish my skills.
Done practice Lesson 1, 2 and 3. 😃

Best of luck to me.
Thanks, Sir Patrick Collins.

facing an error in compiling storagefactory contract

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.7;

import "./SimpleStorage.sol";

contract StorageFactory {

SimpleStorage[] public simpleStorageArray;

function createSimpleStorageContract() public {
    SimpleStorage simpleStorage = new SimpleStorage();
    simpleStorageArray.push(simpleStorage);
}

function sfStore(uint256 _simpleStorageIndex, uint256 _simpleStorageNumber) public {
    // Address 
    // ABI 
    // SimpleStorage(address(simpleStorageArray[_simpleStorageIndex])).store(_simpleStorageNumber);
    simpleStorageArray[_simpleStorageIndex].store(_simpleStorageNumber);
}

function sfGet(uint256 _simpleStorageIndex) public view returns (uint256) {
    // return SimpleStorage(address(simpleStorageArray[_simpleStorageIndex])).retrieve();
    return simpleStorageArray[_simpleStorageIndex].retrieve();
}

}

it says

from solidity:
TypeError: Member "retrieve" not found or not visible after argument-dependent lookup in contract SimpleStorage.
--> contracts/StorageFactory.sol:25:16:

25 | return simpleStorageArray[_simpleStorageIndex].retrieve();
