Помогите создать программу в с++

#include <iostream>
#include <random>
using namespace std;
void fill(unsigned* box, const size_t n) {
uniform_int_distribution<unsigned> uid(10, 99);
mt19937 gen{ random_device()() };
for (auto i = 0U; i < n; ++i) box[i] = uid(gen);
}
size_t even(unsigned* b, unsigned* a, const size_t n) {
auto j = 0U;
for (auto i = 0U; i < n; ++i) if (~a[i] & 1) b[j++] = a[i];
return j;
}
void show(unsigned* box, const size_t n) {
for (auto i = 0U; i < n; ++i) cout << ' ' << box[i];
cout.put('\n');
}
void nf() { cout << " Not found!\n"; }
int main() {
const auto limit = 1024U;
unsigned a[limit], b[limit];
cout << " n: ";
size_t n;
cin >> n;
if (!n || n > limit) exit(0);
fill(a, n);
show(a, n);
auto m = even(b, a, n);
m? show(b, m) : nf();
system("pause");
}

Ок...
