Lesson 2, Calling a view function inside of a gas-calling function

[nkt2pd]

I am calling a view function inside of a gas-calling function (in this case my simple storage function), however, the execution cost does not seem to go up. Anyone else experiencing this or know why this would be the case?

[Ju-Rien]

My experience with view functions called from contracts have been that gas cost do increase. However, a question comes to mind: Is the view function only accessing variables or is it computing and storing temporary variables?
Also, maybe show an example of code that shows this behavior, so that others can check it out :)

@Quent-eth view or pure function when called alone don't spend gas, however if a gas calling function calls them, then it will cost gas, like in this tutorial, I called the retrieve() function inside the store() function

function retrieve() public view returns(uint256) {
        return favoriteNumber;
    }

function store(uint256 _favoriteNumber) public virtual {   
        favoriteNumber = _favoriteNumber;
        retrieve();
    }

There comes a difference of gas costs depending whether the store function is called with or without the retrieve() function.

In my case the transaction cost was 43,746 without calling the view function and 43,886 with calling the view function.

This is a good question

Thats kinda BS if that's the situation...
