提问by slow

Just like in the title, how do you call a base class copy constructor from a derived class copy constructor?

就像标题一样,如何从派生类复制构造函数调用基类复制构造函数?

回答by perreal

You can specify base initialization in the initialization list:

您可以在初始化列表中指定基本初始化:

Derived:: Derived( const Derived& other ): Base( other )
{ /* ... */ }

回答by zindorsky

Derived( Derived const& d )
: Base(d)
/* some member initialization */
{
  /* ... */
}

Am I missing something?

我错过了什么吗?
