Is there an easy way to sort a 2 dimensional array alphabetically by
the second field in each row?
Also, when I use sort() on a two dimensional array, it seems to work a
lot like array_reverse(). Can anyone tell me why?

I'm new to c++ and was wondering how to sort a 2 dimensional array. I'm
using a select sort for 1 dimensional arrays but it is not working for a 2
dimensional array. The 2 dimensional array are float elements. Thanks in
advance

Hi,
Can anyone please tell me how to calculate the size of the following
4-dimensional array, and now to use qsort for sorting on this array?
double sp = { 4.0, 5.0, 6.0 };
double spa = {
{ 4.0, 2.0 },
{ 5.0, 8.0 },
{ 6.0, 6.0 },

I am trying to sort a linked list using insertion sort. I have seen a
lot of ways to get around this problem but no time-efficient and
space-efficient solution. This is what I have so far:
struct node
{
int x;
struct node *next;
};

I think that the operator() member function does not work correctly, does
anyone else know how to make a template for making two dimensional arrays from
std::vectors ??? I want to use normal Array Syntax.

So far, the Articles sections are filled with slow sorting algorithms. Bubble Sort and Selection Sort, while very easy to comprehend, are relatively slow algorithms at Θ(n^2) running time. Here, I will try to explain an algorithm to sort an array of numbers that is fast for small sets of data, though it is still an O(n^2) algorithm; the Insertion Sort.
Suppose we have an array of n-1 elements that is already sorted in increasing order. We...

Hi all,
I have scoured the internet for articles on sorting multi-dimensional
arrays of generic types e.g. T using the IComparer<Tinterface
and have run into a real roadblack. There does not seem to be an easy
way to do this. I have found implementations that use the non-generic
IComparer interface but it seems to me to be more elegant to use
generics if possible.
Has anyone else had this problem and could they suggest or poin me

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
