помогите пожалуйста, программирование, на языке С++ !!!

#include <iostream>

#include <algorithm>

#include <iterator>

#include <random>

#include <array>

const size_t

N = 5,

M = 10;

int main()

{

std::random_device rnd;

std::default_random_engine generator(rnd());

std::uniform_int_distribution<int> dist(-10, 10);

std::array<int, M> arr[N];

std::for_each(arr, arr + N, [&dist, &generator](auto& var)

{

 std::for_each(var.begin(), var.end(), [&dist, &generator](auto& var1)

 {

  var1 = dist(generator);

 });

});

std::for_each(arr, arr + N, [](auto& var)

{

 copy(var.begin(), var.end(),

  std::ostream_iterator<int>(std::cout, " "));

 std::cout << std::endl;

});

std::cout << std::endl;

size_t count = 0;

std::for_each(arr, arr + N, [&count](auto& var)

{

 std::cout << count++ << " | " << std::count_if(var.begin(), var.end(), [](const auto& var) { return var > 0; }) << std::endl;

});

std::system("PAUSE >> void");

return 0;

}
