Jsoncpp parses and assembles Arrays

Array creation and analysis:

Example 1:

String strvalue = "{\" LDH \ ": \" 001 \ ", \" GFC \ ": \" 002 \ ", \" yyj \": \ "003 \", \ "Andy \": [\ "005 \", \ "123 \", \ "True \"]} ";

Example 2:

It was awkward to use jsoncpp at first. For example, there are three arrays in the third example, but val_array [nindex] cannot be used directly. asstring. the format is indeed not clear.

To sum up, no matter which form of array, you can directly look at the content of its corresponding index during parsing, and then we can export its resolution method.
