vector: There are vectors in functional languages too, like this package unordered_set – Unordered/ordered refers to the underlying implementation; how the elements are actually stored. vector.cend – cend is a constant iterator pointing to the end. Constant iterators don’t let you modify the value pointed to by the iterator. emplace – Emplace is like insert … Read more
Soundcloud’s developer docs state that each playlist contains an array of tracks (see https://developers.soundcloud.com/docs/api/reference#playlists). You should be able to loop through the array and populate the html with the relevant values by effectively joining the code in your question together, though you will want to either use classes in the markup or generate individual IDs … Read more

Perl extensions are typically .pl or .pm right? .py is for python I think. Anyway, you can kill a specified program in a Unix environment with something like: system ‘killall’, ‘some_program_name’; or system ‘kill’, ‘-15’, $pid; if the variable $pid holds the pid of your program. 4 solved How do I stop a process running … Read more
First of all, they all have undefined behavior for the same reason: They will read a number of characters you can’t know in advance, but through your pointer, you provide storage where to store this data, and this storage has some fixed size. Therefore, there are always inputs possible that will overflow your buffer. You … Read more
