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

Instead of using a raw array, why not use a vector instead.

class SomeType {
  vector v;
  SomeType(size_t x): v(x) {}
};

Using a vector will give you automatic leak protection in the face of an exception and many other benefits over a raw array.
