c: init array with string literals not introduced. (#2369)

Browse Source 
* c: fix using pointer before introduced.

* c: init array with string literals not introduced.

To avoid using the concept pointer before it has been introduced,
previously it is changed to array.
But as @geoffliu pointed out,
array initialization using string literals is not introduced either.
So this commit uses neither pointer nor array.
Discussing `i++` and `++i` does not need to involve pointer or array.

* c: use `var = value` instead of `->`.

`->` is typically used for functions.
Thanks, @vendethiel.
