隐式类型系统一个较大的优点是，不需要为函数的参数声明类型，因为编译器会从传入的值推断出参数的类型。

One big advantage of type-inferred systems is that you don't need to declare the types of arguments to a function because the compiler infers them from the parameters you pass in.

它包括所有类的数据成员，所有类的成员函数(或者显式声明，或者由编译器隐式生成)，所有类的基类和所有它们的成员。

It includes all class data members, all class member functions (either explicitly declared, or implicitly generated by the compiler), all base classes of the class, and all their members. Consider.

一个隐式声明的构造函数是这个类的一个内联公有成员。

An implicitly-declared default constructor is an inline public member of its class.
