如何实现类似于std :: vector的自定义类

Question

My topic question is a little misleading, I dont want to implement a whole class like a std::vector but I want to be able to create a class called Container so I can declare it like so:

Container <unsigned int> c;

So is this how I overload the <> operator...

class Container
{
   private:
      Container() 
      {
         ...
      }

   public:
      void operator <>( unsigned int )
      {
         // what do I put here in the code?
         // maybe I call the private constructor...
         Container();
      }
};

Answer 1

There is no operator <> . The <> denotes that Container is a class template . You need syntax along the lines of:

template <typename T>
class Container
{
    ...
};

The best place to start is to find a good C++ book, but you could also try reading eg the C++ FAQ page about templates .

Answer 2

You should learn more about templates.
http://www.cplusplus.com/doc/tutorial/templates/

In a nutshell, what you want is:

template <class T>
class Container {
    ....
};
