Why Solidity Inheritance Parent and Child have their respective values?

Question

I need to split my smart contract because of the size limit, so I created Inheritance. Never did it before. But I got into trouble, I tried to go back to basics and try this code :

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;


contract parent {
  
  uint256 internal id = 9;
  
  function setValue(uint256 _value) public{
      id = _value;
  } 
  
  function getValue1() public view returns (uint256) {
    return id;
  }
}

contract child is parent {
  
   function getValue2() public view returns (uint256) {
        return id;
   }
}

Deployed the above contracts on Remix and my question is:

Why when I set Value on parent contract, it can't be read from child contract.

Why Parent and Child have their respective values with the same function?

Need explanation from expert.

Answer 1

From what I can see, it can be read.

If the id variable was declared private and not internal in that case, you'd not be able to access it from child smart-contract

Screenshot from remix - on the contract specified above. Maybe you just had a mistake and deployed parent - instead of child contract.
