QUESTION
I want to simulate the customers entering the queue from the array one at a time and collect data when they both enter the queue or leave the queue to be served by the tellers. Read the data from the file into an array which I did, I would like to know how to dequeue, enqueue and display the customers that left or enter from the array text file (35 people). For example: I want to remove the first customer ID is 1, I chose 2 (removeCustomer()), it will remove that person and when I display the remaining customers (displayCustomer()), it will only display customer with ID 2 to ID 35, and when I choose 1 (nextCustomer()), it will add the person with ID 1 back in line after ID 35.
Below is what I've done so far. I have tried many methods but none of them worked. I'm not sure what I missed or did something wrong. Thank you.

Answered 2021-Mar-04 at 21:14You could try using the C++ standard library queue and stack libraries. std::queue might be good to use for the customer queue since it models quite well the real situation.
Though I am not completely sure what you wish to do, I modified the code to show one way to organise your customer objects using the above libraries. (Other useful libraries might be std::map, std::list and std::vector) Using std::stack and std::queue is complicated a little when you need to iterate through the elements to display them, because they don't provide access to middle elements, but it can be done by copying elements to a temporary container then back again as shown in the below code:
(If are required to use raw arrays, then you could try implementing your own queue functionality using functions on arrays, but a useful feature of the std::containers is that they have functions that tell you how many elements they currently have, so you dont need to store sizes separately as ints, which removes some code)

I'd like to create a property wrapper to accommodate the well known precision issues. However, when I use the @PropertyWrapper
as I understand it to be used and demonstrated here, I get the following errors:
ANSWER
Answered 2021-Feb-05 at 03:39According to the docs:
When you include property wrapper arguments, you can also specify an initial value using assignment. Swift treats the assignment like a
wrappedValue
argument and uses the initializer that accepts the arguments you include.
So it translates your property declaration into something like:
QUESTION
My if statement works in terms of control flow- i.e. it catches the condition and executes or passes accordingly (the second if statement below). However, when I call the compiled program with the value 2 ./bankers.c 2
, the value of num_processes reverts to 0 and prints 0 to console, as opposed to 2. When I uncomment the second call to that function, outside of if(), then it works. Shouldn't it populate the variable no matter what as that function is being called? I know you can call the fork() function inside the if statement. This is more a theory question.

QUESTION
I'm attempting to sync a gif to the beat of music playing on Spotify, but I'm encountering a speed issue while doing so. I must be going crazy because I can't find a reason as to why this isn't working. Below is my methodology:
- Take initial BPM (ex: 150) and find the Beats/Second (
BPS
)BPS = BPM / 60
- Find the Seconds/Beat (
SPB
) from the Beats/Second (BPS
)SPB = 1 / BPS
- Find the Seconds/Loop (
SPL
) by multiplying by the number of Beats/Loop (BPL
) of the .gifSPL = SPB * BPL
- Convert Seconds/Loop (
SPL
) to Milliseconds/Loop (MSPL
)MSPL = SPL * 1000
- Divide the Milliseconds/Loop (
MSPL
) by the number of frames (num_frames
) in the .gif to find the time required for one frame (frame_time
), rounding to the nearest even number since .gif frame times are only accurate up to whole millisecondsframe_time = MSPL / num_frames
- Add up the total frame times (
actual_duration
) and loop through frames adding or subtracting 1 millisecond untilactual_duration
matchesceil(MSPL)
(always prioritizing longer actual duration over shorter duration)...
ANSWER
Answered 2020-Jun-02 at 21:18Solved! I don't know if this is a limitation of the .gif format or if it's a limitation of the Image module in PIL, but it appears that frame times can only be accurate up to multiples of 10 milliseconds. Upon inspecting the actual frame times of the modified image, they were being floored to the nearest multiple of 10 resulting in an overall faster playback speed than expected.
To fix this, I modified the code to choose frame times in increments of 10 (again prioritizing a longer actual duration if necessary) and dispersing the frame time adjustments as evenly as possible throughout the list:

QUESTION
I'm trying to create a dashboard, where upon selecting a company from a dropdown list, it will list all of the company's bankers where the data is on another worksheet tab.
So far, the Index Match formula seems to be running fine, however, it keeps on running and lists the bankers from other companies. How can I fix this?

QUESTION
I'd like to calculate % of stocks above rolling mean, therefore, I need to group the data by 'Date' and want to keep the 'Date' column. Percentages are calculated correctly, however, instead of actual dates I'm getting 'NaN' values. The 'Date' column is not the data frame index.
...ANSWER
Answered 2020-Jan-09 at 16:02You have to remove the 'Date'
from the [ ], you are already grouping by it. And don't drop the index, Date
is your new index in your returning dataframe and you want to keep it
