For a public state variable, an automatic getter function is generated.  Internal state variables can be accessed only internally from the current contract or contract deriving from it without using this.  Private state variables can be accessed only internally from the current contract they are defined not in the derived contract from it. Example of   Public vs Internal vs Private state variables pragma solidity ^0.5.0; contract C {    uint public data = 30;    uint internal iData= 10;        function x() public returns (uint) {       data = 3; // internal access       return data;    } } contract Caller {    C c = new C();    function f() public view returns (uint) {  ...
