помогите сделать 1 и по возможности 2 на c++

include lt;iostreamgt;

include lt;clocalegt;

include lt;arraygt;

include lt;algorithmgt;

include lt;iteratorgt;

include lt;randomgt;

include lt;numericgt;

const size_t

 N = 5,

 M = 4;

int main()

std::setlocale(LC_ALL, "Russian");

std::random_device random;

std::default_random_engine generator(random());

std::uniform_int_distributionlt;intgt; dist(-100, 50);

std::arraylt;int, Mgt; arr[N];

std::for_each(arr, arr+N, [amp;dist, amp;generator](autoamp; var)

 std::for_each(var.begin(), var.end(), [amp;dist, amp;generator](autoamp; var)

  var = dist(generator);

 );

);

std::for_each(arr, arr+N, [](autoamp; var)

 std::copy(var.begin(), var.end(),

  std::ostream_iteratorlt;intgt;(std::cout, " "));

 std::cout lt;lt; std::endl;

);

std::arraylt;int, Mgt; sum_min 0 ;

for (size_t j = 0u; j lt; M; j++)

 for (size_t i = 0u; i lt; N; i++)

  if (arr[i][j] lt; 0)

   sum_min[j] += arr[i][j];

std::cout lt;lt; std::endl;

std::copy(sum_min.begin(), sum_min.end(),

 std::ostream_iteratorlt;intgt;(std::cout, " "));

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

return 0;
