I found a good gh VB example on wiki. In his VB , when he want to find the middle point of two points. he use "points(i - 1) + points(i)) / 2"
I want to know , why this means finding the middle point of two points???? And how does he know this???? In VB examples, I usually find such kind of transcendent thing, how can I learn them? In fact, I am a new learner and want to learn VB for gh. BUT can not find a good way to learn. I have read the 2nd primer, did not get any point. And then I want to recite some VB example , just like the way I learn foreign language, Is that a good way?
