Ответ:

#include <iostream>

#include <ctime>

#include <cstdlib>

using namespace std;

int main() {

 srand(time(0));

 const int n = 20;

 double r = 0;

 int a [n];

 for (int i = 0; i < n; ++i){

   a[i] = (rand() % (50-0+1)+0);

   cout << a[i] << " ";

   r = r + 1.0 / (double)a[i];

 }

 cout << endl;

 r = 1.0 / r;

 cout << "R: " << r;

}
