A docx file is actually a zip file. Try renaming it to xyz.zip and unzipping it. You'll find a number of files in a number of folders, most of which are XML files. These XML files have a specific format, created by MS for docx files.

You could try to do all that directly in python (or whatever language you want) including what all the XML attributes and elements mean and how the different files relate to each other, or you could use a library which already knows that.

As to your second question you have presented no data which would allow me to even guess, so I won't.

Your problem is the student_info function, the file only contains None because if a function doesn´t return something the default behavior is to return None. When you are doing str(student_info(sname,sage,sgender) you are calling the __str__ method of the None class, that return the string "None". So, the correct way is returning a string, instead of printing inside the function:

I believe your goal as follows.

• You want to retrieve the values from Firestore and you want to create a HTML table using the retrieved values using Google Apps Script.

When the sample value of allDocumentsRows = firestore.getDocuments("StudentInfo") is the values in your question, and the header row is ["Age", "Fname", "Lname", "StudID", "Gender"], the sample script is as follows.

As mentioned by King King, creating a custom UserManager seems to be the way to go. However, what I have ended up using is the much simpler approach mentioned by Prolog using the UserManager.Users property which is an IQueryable and hence the Include() method can be called on it:

You may use kotlin.io readLine as you have tried. You just need to cast what you need. If you want to take Double just do val value = readLine().toDouble() You can also create functions for simplicity such as,

fun readInt() = readLine()!!.toInt()

Or, you may use legacy scanner way.

Change your code like below:

Why does the syntax itself have (void *) in void *malloc(size_t size).

Because malloc is a function and functions have a return type. This tells that this function returns this particular type. So (void *) means malloc return a void *.

Does the malloc function return an address or something after it has assigned a memory block?

Malloc allocates the memory of the size specified into the heap and returns a pointer to that allocated memory.

In this we are assigning the studentInfo pointer the malloc function right? So... how does studentInfo know that the address of the memory block is USA and not Antarctica??

Not exactly. studentInfo is not assigned the malloc function but studentInfo points to the pointer returned by malloc. This was studentInfo now points to the allocated memory.

Why does malloc need a pointer??

malloc doesn't need a pointer. It takes the amount of memory you want to allocate as an argument.

You don't need to typecast here, as void * is automatically promoted.

And one more thing is it necessary that we need the typecast to be in brackets?

Yes, that's the syntax for typecasting. Without brackets, it will result in compilation errors.

Your code should allow the user to skip the input, let's say, by pressing enter, leaving the buffer empty, I mean with \0 only, you could use fgets for this, but a problem remains, if the input is larger than what the buffer can take, the remaing contents on stdin will be left there, compromising future readings.

I'd suggest using a more personalized method:
