Here is the base R solution:

Based on further requirement as stated in comments to turn the solution into a function foo, this may meet the requirements

I don't know if it is better, but there is shorter argument to do this

I'll take on the particular case of C, since it's hard to answer questions about hypothetical situations in hypothetical languages. Still, the concrete issues raised by parsing C are probably indicative of the kind of strategy you might use to handle other concrete issues. In any event, much of the content of a textbook like the Dragon book (or any other text on compiler construction) needs to be read as an exploration of possibilities rather than as a recipe-book. If there were a few recipes which could be copied, the topic would be much less interesting.

Not counting macros (which are a totally different discussion), C has three general namespaces plus a namespace for each composite type (that is, structure and unions). These are listed in §6.2.3 of the C standard:

1. statement labels.

2. tags used to identify struct, union and enum types.

3. ordinary identifiers, which can be variable names or type aliases.

These namespaces are completely separate; the use of a name for a label or the tag of a union type does not have any relationship whatsoever with its use as a variable or a type alias, and neither of those have any relationship with the use of the same identifier token to name members of one or more aggregate types. Although it's very simple to decide which namespace a particular token should be looked up in, doing so requires a some context (quite a bit in the case of member names) and its not very likely that the work will be done in the lexical scanner. So it's reasonable to assume that the lexical scanner will intern identifiers in some kind of catalog of names (to avoid unnecessary copying of identifier strings), and leave it to the parser to use the identifier as it sees fit.

In most cases, the namespace can be almost immediately resolved, and the actual symbol table entry will be created in the appropriate syntax table through an attribute rule in a syntax production (or the moral equivalent in compilers which are not strictly syntax-driven).

For example, an aggregate tag always follows the token enum, struct or union in a type declaration, while a label is always followed by a : and a statement. The relevant productions are unambiguous and relatively low-level, and a newly-created identifier can easily be entered into the correct symbol table before any possibility of another use of the same identifier in the same namespace.

Here's a part of the C grammar:

When you submit your job to the Spark runtime, the Spark jars are already available within the runtime, so you do not need to include them in your jar.

You can set the scope of the scala-library, spark-core_2.11 and spark-sql_2.11 (and any other Spark dependency that you might add in future) to provided. The assembly-plugin will skip these libraries (as well as all of their transitive dependencies), thus reducing the size of your jar. As these jars are already part of your Spark runtime, your Spark job will still work. You should only include libraries in your jar that are not part of Spark, like the com.typesafe:config library.

That is because you are logging the data before it got fetched by the httpClient, keep in mind that the httpClient.get is an async method, if you want you can move console.log to be inside the subscription and it should work correctly:

Using the 'new' (not that new) Java 8 time API:

Really thanks for @mjwills comment and guide. From the error message, the parameter @table was not supplied.

Your followed his suggestion and find that you didn't set the "Value" of SqlParameter in all my mucking about trying different things.

We are glad to hear that the issue is solved. I help post this as answer and this can be beneficial to other community members.

If you want this kind of control over the formatting of a cloze exercise then it is better to use ##ANSWERi## syntax or placing the answer interaction fields where you need them. See the boxhist2 exercise for a worked example.

In your case I would put the following questions before the Answerlist:
