array in struct zur laufzeit initialisieren

[proty]

Also so:

struct ringbuffer
{
   vector<int> array;
   ringbuffer(size_t size) : array(size) {}
};

int main()
{
   ringbuffer rb(256);
   cout << rb.array.size() << endl;
   for (int i = 0; i < 256; ++i)
   {
      rb.array[i] = i+1;
      cout << rb.array[i] << endl;
   }
   return 0;
}

Tausend Dank euch allen
