#include <string>

#include <utility>
#include <iterator>
#include <vector>
using namespace std;
int main()
{
    string line;
    cout << "Please enter 20 integers, positive, negative, or zeros.\n";
    getline(cin, line);
    istringstream this_line(line);
    istream_iterator<int> begin(this_line), end;
    vector<int> values(begin, end);
    int even = 0, odd = 0, zeros = 0;
    cout << "The numbers you entered are\n";
    for (auto i = values.begin(); i != values.end(); ++i){
        int n = *i;
        cout << n << " ";
        if(n == 0) {
            zeros++;
        }
        else if (n % 2 == 0) {
            even++;
        }
        else {
            odd++;
        }
    }
    cout << "\nThere are "<<even + zeros<< " evens, which includes "<<zeros<<" zeros"<<endl;
    cout << "The number of odd numbers is "<<odd<<endl;
