CppScopedArray

---

(C++) boost::scoped_array

a smart pointer available in the Boost C++ Library. It enables you to dynamically create an array that goes out of scope automatically.

//Standard way
{
  const int size = rand()%69;
  int * myPlainArray = new int[size];
  //Code
  delete[] myPlainArray;
}
//Using the boost::scoped_array
{
  boost::scoped_array<int> myArray(rand()%69);
  //Code
  //Nothing! myArray deletes[] itself when going out of scope!
}

Why is the boost::scoped_array not in the STL, where std::auto_ptr is ?

On the website of Bjarne Stroustrup he stated that the boost::scoped_array was not necessary. I guess, this is because a std::vector can be used instead, which has similar behaviour.
