Determine array size in constructor initializer

Question

In the code below I would like array to be defined as an array of size x when the Class constructor is called. How can I do that?

class Class
{
public:
  int         


        

Answer 1

Two options:

Use std::vector. This allows easy re-sizing of the array.
Use std::tr1::array. This has a static size.

Both can be correctly initialized in the constructors initializer list.
