  function addPerson( string memory _name,uint _favN) public{

    Please can you specify what do you do in your code? Do you want to instantiate a struct? Commented Mar 13, 2022 at 11:47

The contract name in struct.sol is storageb and not struct (which is a solidity keyword).

Calling import "struct.sol"; is quite similar to copy&paste content of struct.sol in your storagrFactory.sol

You need to use storageb instead of struct in storagrFactory.sol to make your contract compile.


Try to change your function to this:

function createSimpleStorageContract()  public {
    storageb simpleStorage = new storageb();

Hope it helps!
