C++ Initialize Pointer in Member Initialization List

I am wondering if there is a way I can, in my class' constructors, initialize an array in the base initialization list.

Right now, I am initializing myChars (a char*) to an empty character array of size DEFAULT_SIZE:

    A::A() :
      mySize(0), maxSize(DEFAULT_SIZE)
    {
         myChars = new char[DEFAULT_SIZE];
    }

Is there any way to do this in the base initialization list? So that it would be simply:

     A::A() :
      mySize(0), maxSize(DEFAULT_SIZE), **myChars initialized here**
    {
    }

Thanks!

Did you try?

 A::A() :
  mySize(0), maxSize(DEFAULT_SIZE), myChars(new char[DEFAULT_SIZE])
{}

However, it's extremely recommended to use std::string, std::vector<char>, or std::unique_ptr<char[]> instead, all of which manage memory without error.
