There are two main differences between dynamic typing and static typing that you should be aware of when writing transformation scripts. First, dynamically-typed languages perform type checking at runtime, while statically typed languages perform type checking at compile time. This means that scripts ...

One kind of side point he brought up was tons of projects that are written in a statically typed language end up adding a second dynamic language inside. He basically said given all of the stuff above you should just have used the dynamic language in the first place then get all of the ...
This view is presented in the form of three examples in which a statically typed solution is forced to emulate dynamic type checking in order to do "The Right Thing"^TM. These examples are presented in the form of patterns. However, since they describe widely applied non-working solutions ...
The latter, aPi@, combines static and dynamic typing: a static type system associates channels with flat types that only express read/write capabilities and disregard the payload type, while a dynamically typed synchronization complements the static type system to guarantee type soundness. We show ...

Note that conversion is not the same thing as coercion, IMO. Coercion occurs when you have a statically-typed language and you use the syntactic features of the language to force the usage of one type as if it were a different type (consider the common use ofvoid*in C). Coercion is us...
static vs. dynamic typing, which is completely orthogonal but all too often confused with inference strong vs. weak typing, which is mostly orthogonal (e.g., C is statically typed because every variable has a statically known actual type, but also weakly typed because of its casts) ...
Static vs. Dynamicdefines how a language expects you to declare data types. Static typed languages require explicit definition of a data type when they create a piece of data (e.g. variable, parameter, return value). Dynamic languages are the opposite and can infer, or at least try to gue...
常见四种显示转换方式如下所示,且先从功能强弱上排个序,从强到弱应该是:reinterpret_cast,旧式转换,static_cast,dynamic_cast。 (1)static_cast 用法:static_cast < type-id > ( exdivssion ) 该运算符把exdivssion转换为type-id类型,但没有运行时类型检查来保证转换的安全性。它主要有如下几种用法: ...
