QUESTION
I need to use a Fortran code to solve stochastic differential equation (SDE). I looked at the famous Fortran code website by Burkardt,

I particular looked at the rk4_ti_step subroutine in stochastic_rk.f90 code,

QUESTION
I am trying to parse a json array by using this code
...ANSWER
Answered 2021-Jul-11 at 09:00According to JObject.Parse,
Load a JObject from a string that contains JSON.
For your "q" and "a", it is just a simple string but not a JSON string. Hence you should not use JObject.Parse.
With .ToString(), it is good enough to retrieve the value of q and a.

Here's my C code:
...ANSWER
Answered 2021-Jun-27 at 13:26A FILE * is not a pointer to a file; it is a pointer to a FILE. Per C 2018 7.21.1 2, a FILE is:
… an object type capable of recording all the information needed to control a stream, including its file position indicator, a pointer to its associated buffer (if any), an error indicator that records whether a read/write error has occurred, and an end-of-file indicator that records whether the end of the file has been reached…
Thus fp2=fp1; makes fp2 point to the same object that is used to control the file, so any changes made to the object pointed to by fp1 appear in the object pointed to by fp2 and vice-versa because they are the same object.
qArray++ changes the pointer qArray. fseek(fp2,100l,SEEK_CUR); changes the object pointed to by fp2 (and the stream it controls). Similarly, if you called some routine ChangeAnElementInArray(qArray, index, value), that would change an element in the array; it would not change the qArray pointer.
Also, a FILE * is not a position in a file. It is just a pointer to the data structure that is used to control the stream.

Answered 2021-Jun-20 at 03:56For a module to be initialized it needs to be imported directly or indirectly in the program. This applies to modules in the same package too. Since question_management.question is not imported directly in the default module or in a module that is imported by the default module, the service in question_management.question is not initialized or attached to the listener, which is why this error is observed.
A module can be imported using the import prefix _ to include it in the program without using the symbols in it. This will result in the module being initialized, and the service will then be initialized and attached to the listener [1].
Adding import question_management.question as _; in the default module (main.bal) will result in the service in question_management.question being attached to the listener, and invoking /questions/allQuestions should work as expected.

QUESTION
So I am still a little confused about pointers in connection with structs.
I have a struct which represents a queue. The queue contains an array of queue elements (containers).
I now want to access these containers in order to assign values to them. This code is only for containers[0] to keep it simple.
How can I access the string at containers[0] in main after returning from writeContainer() function?
The signature of writeContainer() is given, so I can't change that.

I have a web app which take some inputs and I need to write those inputs in a sheet and then send an email with those inputs.
My code is below, I removed some lines in the code because they are not relevant. Assume pnArray and qArray are two arrays with values (strings and numbers).
The problem statement is how to create a HTML table in the loop below and then send that table by email.

QUESTION
I am using google web app to create a web user form. I have 10 drop down lists (select elements) in a table.
I have a code which loop through all the "select" HTML elements (At the moment I am debugging using only 2 of them) once a button is clicked. I am getting a very weird error, which I do not understand at all. The loop should be through 2 elements, but somehow the code end up looping through 8 elements. 6 of them do not exist!
Extracted HTMLselect elements (id = pn1, id = pn2):
...ANSWER
Answered 2020-Jul-01 at 17:16The issue is because of using the for...in loop on a NodeList.
As you can see in the console you get a NodeList when you use var selectElements = document.querySelectorAll('[id^=pn]')
Don't use for...in or for each...in to enumerate the items in NodeLists, since they will also enumerate its length and item properties and cause errors if your script assumes it only has to deal with element objects. Also, for..in is not guaranteed to visit the properties in any particular order.
As mentioned here.

Install qarray
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
