C++ - how to fill a dynamic array with elements less than 6 from another dynam. array?

Question

C++ / C#

You need to enter a sequence of numbers and create a dynamic array, and then form another array, in which there will be elements of the first array, only less than 6. I made a random number generator that generates new numbers when it starts. There is a counter that is equal to the number of entered numbers and a counter for the 2nd array. All this to create these dynamos. arrays.
Now the problem itself: I don’t know how, in the FillNewArray function, to implement filling the second array with elements of the first one, the values ​​of which are less than 6. I attach the code below:

#include "stdafx.h"
#include <iostream>
#include <ctime>

using namespace std;

int FillNewArray(int Array[], int count, int LesArray[], int Lesser)
{
  for (int i = 0; i < count; i++)
  {
    if (Array[i] < 6)
    {
      LesArray[i] = Array[i];
    }
  }
  return LesArray[Lesser];
}

void ShowArray(int Array[], int count)
{
  for (int i = 0; i < count; i++)
  {
    cout << Array[i] << "\t";
  }
}

int main()
{
  srand(time(0));
  int count;
  int Lesser = 0;

  cout << "Input the size of your array: ";
  cin >> count;

  int *Array = new int[count];

  for (int i = 0; i < count; i++)
  {
    Array[i] = 10 - rand() % 20;
    if (Array[i] < 6)
    {
      Lesser++;
    }
  }

  cout << "The array: ";
  ShowArray(Array, count);

  int *LesArray = new int[Lesser];

  FillNewArray(Array, count, LesArray, Lesser);
  cout << "\nChanged array: ";
  ShowArray(LesArray, Lesser);

  system("pause>>void");
  return 0;
}

Answer 1

int FillNewArray(int Array[], int count, int LesArray[], int Lesser)
{
  int j = 0;
  for (int i = 0; i < count; i++)
  {
    if (Array[i] < 6)
    {
      LesArray[j++] = Array[i];
    }
  }
  return LesArray[Lesser];
}

Do you have C++:

#include <algorithm>
...

std::copy_if(std::begin(srcArray), std::end(srcArray), std::begin(dstArray), 
             [](auto && elem) { return elem < 6; });

Ну там back_inserter в случае вектора может быть. Кстати, в С++ надо использовать vector или array.
Как сделать генератор случайных чисел можно посмотреть тут: www.cplusplus.com/reference/random/.
Итого, ваша задача сведётся к 4-5 строчкам кода.
