Why does the indexing start with zero in 'C'?
...out the above reasons
While Dijkstra's article (previously referenced in a now-deleted answer) makes sense from a mathematical perspective, it isn't as relevant when it comes to programming.

Now, it is sure against intuition that a sequence of code does not flow "top-down", instead it runs as if there was no sequence at all - and may be called "devil's playground". I believe it is infeasible to give an exact answ...

What is the difference between a var and val definition in Scala?
...ge the state of that object. At the root of it, however, there was a var.

x = new B(0)
f(x)
if (x.value.value ...
