Thank you for your reply, I'd like to ask why there'd be 2 14 secondary page tables instead of the size of secondary page table being 2 14.
As I understand, primary page table will hold the address to a single secondary page table. Perhaps I'm mistak...

"Involving code" means the code will be given and we'll have to either debug explain the code given to us. NO CODE WRITING is necessary. (Look at literally any last 4 lectures and you can find Amitava stating this over and over)

It doesn't matter. As long as the point comes across, write it in your assumptions since most of these are just formatting. As long as it is clear what is what, you'll be fine

It is incorrect, the first 1 will be loaded at time 4 (for both ignore and not) while the second 1 will be loaded at time 7 if you ignore and 9 if you don't.
ANONYMOUS wrote
These are correct. C
Clarification for if anyone else looks at this. OP has decided to ignore calls if all has been loaded. It would look different if you chose to load it again.
Adding to this to show how it'd look if you chose to ignore it instead of pushing

You can write is as an assumption that it will always be named that. This is a simple project so I doubt they'd check it. But a good practice is to not hard code it but instead let it work with any names. Hope this helps

I have emailed Amitava this and he says it doesn't matter how you put it (99, 99, 0 or Empty, Empty, 0 or Empty, Empty, Empty) just put it under your assumptions as comments at the very top of your code

I don't think it matters, as long as it is obvious that it is page table RAM content. Also you should clarify for your project, you chose to load the process to RAM again instead of ignoring it. Below is how it'll look like if it was ignored

Amitava has already mentioned multiple times during multiple lectures that there will be no code writing questions. At most he will give a code snipet and we will have to explain it. Please watch his lectures, it is actually useful
I see So when we remove it from RAM we just remove the pointer to it in the RAM while the pointer in the Virtual Memory never changes?
And yes, I was asking if they were separate arrays. Thanks for the help Joshua

Not sure if I am correct but the reason why B (int x 2 10;;) is because it would take the second semicolon as an empty statement so it'll be read as

Not OP but would it be because it depends on the bits (i.e. 32-bit or 64-bit) where 32-bit is 4 bytes per integer but something like 16-bit will give 2 bits so it'll be value of 200.
That's why the answer is B. Because the value byte of each object i...
