Careful when you override / redeclare the same variable in a child contract

base_test.sol

pragma solidity ^0.5.0;

contract Base {
    
    string name = "Parent Name";
    
    constructor() public {
        
    }
    
    function getName()  public view returns (string memory) {
        return name;
    }
    
    function setName(string memory newName)  public {
        name = newName;
    }
}


contract Child is Base {
    
    // overriding this is a very bad idea
    string name = "Child Name";
    
    // setName() will work with super.name
    // getName() will work with super.name

    function getChildName()  public view returns (string memory) {
        return name;
    }

    function getParentName()  public view returns (string memory) {
        return super.getName();
    }
}

Very helpful
