Compiler | A simple compiler front end

Giving a bit of context. I'm using c++17. I'm using pointer T* data because this will interop with cuda code. I'm trying write a parallel version (on CPU) of a histogram creator. The sequential version:

So I created a poll model in my Django app. I'm going thorugh the polling app tutorial posted on the Django website, however, I'm using a remote MySQL database rather than a SQLite database.

I am trying to create an app in which the user has the option to query the database by entering information into one of two entry boxes. I want to be able to use a single select statement and conditionally query the database based on what box the user enter their information into. I currently am trying to use a CASE clause, but I believe that it is running into an error when I try to include a WHERE clause in the THEN argument. Here is what I am currently working with:

My Question: What exactly does “compile-time” mean? I present my understanding below and where I am getting confused.

Compilation is the process that generates a single executable .exe file from the .vb file. There are several ways to do this, for example by using the VBC.EXE command from the developer command window or MSDOS. The way I understand “compile-time” is that it is time when such a command gets executed and the exe file is generated. The following are the what I find confusing:

1. When I write Dim i = 5, the compiler infers or “knows” that the variable “i” is an integer.
2. If I want to print an integer or a string using the Writeline method of the console class then the compiler automatically determines which overloaded version it should call. So in this case also the compiler “knows” – this is also known as compile-time polymorphism.

My confusion: Since in both the above cases the compiler infers or knows the type of variable or the version of the overloaded method to call just after we have finished typing the sentence, is this also called compile-time? We have not given any sort of compilation command here.

1. Another confusion on the definition of compile-time refers to the case when we explicitly define overloaded methods. In the case of the writeline method, we know from the pop-up given by intellisense that immediately after we have finished typing the sentence the version with the correct signature is called. Now, when we define overloaded methods does the compiler know which version to call when we call the function (depending on signature) somewhere in the program right after we have finished typing the code? Or does the compiler know this after the exe file has been generated? This is a case of compile-time polymorphism. But then which time or which step is the “compile-time”?

I ran into less than ideal inlining behavior of the .NET JIT compiler. The following code is stripped of its context, but it demonstrates the problem:

Consider the following code:

I'm using glutin and so have a move closure for my program's main loop and I'm trying to play an audio file with the rodio crate. With the following code everything works and I get one beep every time the program loops:

I am aware that floating-point numbers are tricky. But today I encountered a case that I cannot explain (and cannot reproduce using a standalone C++ code).

The code within a large project looks like this:
