The C++ matrix needs to be done exactly as in the photo (which is in the center) And replace the numbers that indicate the arrows with the numbers SU.?

Question

C++ / C#

Answer 1

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
  srand(unsigned(time(0)));
  size_t n = 2 * rand() % 6 + 5, m = n;
  int** array = new int* [n];
  for (auto x = 0; x < n; x++)
  {
    array[x] = new int[m];
  }
  for (size_t x = 0; x < n; x++)
  {
    for (size_t y = 0; y < m; y++)
    {
      array[x][y] = 0;
    }
  }
  unsigned h = 1; int p = 1;
  for (size_t y = 0; y < m / 2; y++)
  {
    if (n - h == 0)
    {
      break;
    }
    for (size_t r = h; r < n - h; r++)
    {
      array[r][y] = p++;
    }
    h++;
  }
  for (size_t y = m / 2; y < m; y++)
  {
    if (n - h == 0)
    {
      break;
    }
    for (size_t r = h; r < n - h; r++)
    {
      array[r][y] = p++;
    }
    h--;
    if (!h)
    {
      break;
    }
  }

  for (size_t x = 0; x < n; x++)
  {
    for (size_t y = 0; y < m; y++)
    {
      cout << setw(5) << array[x][y];
    }
    cout << endl;
  }
  return 0;
}

Answer 2

Which linux distribution to choose?

Any. All the talk about some radical difference is blah blah blah.
The selection criteria can be:
- the number of users, the size of the community
- the availability of documentation, descriptions If you
want the latest - install Fedora.
If you want a minimum of hassle, install Mint.

Answer 3

Depends on goals. Install the required stability with Debian.
