Question

I want to statically allocate the array. Look at the following code, this code is not correct but it will give you an idea what I want to do

class array
{
  const int arraysize;
  int array[arraysize];//i want to statically allocate the array as we can do it by non type parameters of templates
public:
  array();
};

array::array():arraysize(10)
{
  for(int i=0;i<10;i++)
    array[i]=i;
}

main()
{
  array object;
}

Answer 1

If your array size is always the same, make it a static member. Static members that are integral types can be initialized directly in the class definition, like so:

class array
{
  static const int arraysize = 10;
  int array[arraysize];

  public:
    array();
};

This should work the way you want. If arraysize is not always the same for every object of type array, then you cannot do this, and you will need to use template parameters, dynamically allocate the array, or use an STL container class (e.g. std::vector) instead.
