running into decleration error in solidity course

Question

just started a solidity coding course and ran into this issue with this code:

//SPDX-License-Identifier: MIT

pragma solidity >=0.6.0;

import "./simplestorage.sol";
``
contract StorageFactory {
function createsimplestoragecontract() public {
simplestorage _simplestorage = new simplestorage();
}

}

I'm running into this error: DeclarationError: Identifier not found or not unique. --> contracts/storageFactory.sol:9:9: | 9 | simplestorage _simplestorage = new simplestorage(); | ^^^^^^^^^^^^^

Answer 1

The following code worked fine for me.

 //SPDX-License-Identifier: MIT

 pragma solidity >=0.6.0;

 import "./1_Storage.sol";

 contract StorageFactory {

      function createsimplestoragecontract() public {
           Storage _simplestorage = new Storage();
      }

 }

Did you check if the name of the contract in simplestorage.sol is "simplestorage"? Usually is Pascal case (not mandatory, but good practice), something like SimpleStorage. Be aware about this. Your error probably is about lowercase instead of uppercase.
