请教：动态语言和静态语言最本质的区别是什么？

琴弦上的熊

statically typed language

A language in which types are fixed at compile time.
Most statically typed languages enforce this by requiring you to declare
all variables with their datatypes before using them.
Java and C are statically typed languages.


dynamically typed language

A language in which types are discovered at execution time;
the opposite of statically typed.
VBScript and Python are dynamically typed,
because they figure out what type a variable is when you first assign it a value.

难道是由变量的类型来决定的？？

Thanks.But I still have another problem.
I wonder if it's possible for a scripting language be statically typed, or are there some implemented statically typed scripting language?

静态语言和动态类型语言的本质区别是：对变量类型的检查是静态还是动态[B]为主[/B]。
其中静态包括：C++ Java 等 动态有Smalltalk Ruby Python Lisp
静态的好处是可以很容易地省去运行时的错误处理，而动态语言能提供一个宽松的编程环境。
C++提供了良好的静态类型检查，而相对而言，对动态类型检查却支持较少（可能RTTI算一个）。
