Question

Помогите сделать 1 и по возможности 2 на c++

Answer 1

#include <iostream>

#include <clocale>

#include <array>

#include <algorithm>

#include <iterator>

#include <random>

#include <numeric>

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_distribution<int> dist(-100, 50);

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& var)

 {

  var = dist(generator);

 });

});

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

{

 std::copy(var.begin(), var.end(),

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

 std::cout << std::endl;

});

std::array<int, M> sum_min{ 0 };

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

{

 for (size_t i = 0u; i < N; i++)

 {

  if (arr[i][j] < 0)

   sum_min[j] += arr[i][j];

 }

}

std::cout << std::endl;

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

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

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

return 0;

}
