I have a POD struct S with const members and a std::vector<S> vec that I’d like to sort. The following won’t compile:

I am learning sorting algorithms using C++ , and I want to use ready-made functions in the language libraries. The std::sort(); function is easy to use and understandable, but std::qsort(); I did not understand exactly how it works, especially the comparison function.

I am looking for an algorithm that sorts every N element of an array.

Good evening. It’s been a few days since I’ve been able to convert this algorithm to sort a three-dimensional array. It should sort P two-dimensional matrices by columns “through” the whole array, not each column separately. The whole program code would not fit here, so I attach a small demo version. The algorithm for the vector is working, there are no errors in it. Can anyone help me? I sincerely do not understand what can be the error. Thank you for your time.

Code:

it’s embarrassing to ask this, but please could you help me adapt this algorithm to a two-dimensional array, so that it sorts the whole matrix across columns? This is an assignment from my university, the deadline is tomorrow and I can’t get anything done. Thank you for your time.

I have a question about sorting with C#. I want to implement a function to sort an array of strings such as [“AA”, “A”, “Z”, “ZZZ”] alphabetically without any built-in sort methods. I have tried some Compare function and my logic which is comparison between each character of the two strings, but it does not work properly.
