QUESTION
I am trying to have an object with a set of pointers to another object. when I try to erase on of the set's values I get an error and crash, I really dont know what could be causing it. here is the library and after that the main function: when I try to run it it does everything its supposed to do, and when it gets to the removeemployee it crashes and sends out the following: Process finished with exit code -1073740940 (0xC0000374)
I run it on clion if that matters, and in c++11.

QUESTION
I'm trying to remove the employee in my code and change his salary back to 0, but all I get in the function is his id. I used the built in iterator for the set, but found out that it is const. How can I use mutable, or some other way to change his salary to 0? I have an employee and a manager- the manager can hire or fire the employee, which will change his salary (obviously). This is my code:
...ANSWER
Answered 2022-Jan-06 at 10:26That's not how it works. You can change a value through a const reference, if the member is marked mutable (mutable int salary;
) not the iterator.
However, why do you want to set the salary to zero just before you delete it? And anyway, changing values in a set is not allowed if it affects the order of that set, so generally a bad idea.
QUESTION
I need to convert the CRS of a GeoDataFrame from EPSG:2145 to EPSG:3857. When I use the .to_crs method, it will only transform the x coordinate, leaving the y in the old format.
My original gdf
with EPSG:2145
ANSWER
Answered 2022-Jan-04 at 08:32- this investigation shows that the starting CRS is not EPSG:2145 but is EPSG:4326
- you could use
set_crs()
to change your geodataframe to EPSG:4326 to start
QUESTION
I'm trying to create a product menu on a website where products can have different sizes and prices. I think I've got the tables in 3FN where there's a table for product names, one for product sizes, and one for product prices. The reason for this separation (as best as I can understand) is that each product will have different sizes and prices, but some products will have the same price when those products' sizes are different. To link these, I've created 3 MTM tables - products and sizes, products and prices, and prices and sizes. What I'm trying to do now is query all of the tables at once so that each product-size-price combo is retrieved correctly so that I can then pass that into the PHP page and display the results as part of the menu. Below you can see where I've partly managed to do so using two tables, but I need to join the information from all 3.

Answered 2021-Nov-08 at 17:15After consulting with my team, I found out that you can have a multi-MTM table, from which you can pull all your relevant data simultaneously. See the below model for reference:
To pull relevant information from this table, the command would be something like:

I'm trying to generate rows of sequences, within a function, for each row in my dataset. The problem I'm running into is that the seq
function errors out because I have multiple rows. I've included an example dataset and my code (sequence call is third from bottom of my function).

Answered 2021-Oct-26 at 14:10If you want to apply dur
function for each row, you can use any of the apply function.
For example, with Map

QUESTION
I'm trying to make a copy constructor for Game. throughout the copy constructor I have to copy the elements of one game into another. However when I try to access the inner elemnts of the game I want to copy I get an error saying :
...ANSWER
Answered 2021-Aug-28 at 11:50The []
operator of a vector expects a size_t
argument. You are passing an iterator which is why it doesn't compile.
other[row][col]
can be replaced with just *col
. game[row][col]
is a little more tricky, you can't use the row
and col
iterators with game
as they are from a different container. You can convert the iterators to numeric indexes by subtracting them from begin
, e.g.: other[row - other.game.begin()][col - row->begin()]
. This gets quite hard to read so you might be better off either using two separate iterators for each container or just using indexes for both containers.
The better solution is to let the standard library do the work for you:
