22. Arrays of instances can be declared

Of course, it is possible to declare arrays of objects:

using namespace std;
#include 
#include 

class vector
{
public:

  double x;
  double y;

  vector (double a = 0, double b = 0)
  {
     x = a;
     y = b;
  }

  double module ()
  {
     return sqrt (x * x + y * y);
  }
};

int main ()
{
  vector s [1000];

  vector t[3] = {vector(4, 5), vector(5, 5), vector(2, 4)};

  s[23] = t[2];

  cout << t[0].module() << endl;

  return 0;
}

Output

6.40312
