檢視所有 Wikipediahttps://en.wikipedia.org/wiki/Type_safetyProgramming languages are often colloquially classified as strongly typed or weakly typed (also loosely typed) to refer to certain aspects of type safety. In 1974, Liskov and Zilles defined a strongly-typed language as one in which "whenever an object is passed from a calling function to a called function, its type … 查看更多內容
In computer science, type safety and type soundness are the extent to which a programming language discourages or prevents type errors. Type safety is sometimes alternatively considered to be a property of … 查看更多內容
Type safety is usually a requirement for any toy language (i.e. esoteric language) proposed in academic programming language research. Many languages, on the other hand, are too big for human-generated type safety proofs, as they often require checking … 查看更多內容
In object oriented languages type safety is usually intrinsic in the fact that a type system is in place. This is expressed in terms of class definitions.
A class essentially defines the structure of the objects derived from it and an API as a contract for … 查看更多內容Intuitively, type soundness is captured by Robin Milner's pithy statement that
Well-typed programs cannot "go wrong".
In other words, … 查看更多內容In isolation, type soundness is a relatively weak property, as it essentially just states that the rules of a type system are internally consistent and cannot be subverted. … 查看更多內容
Type safety is closely linked to memory safety. For instance, in an implementation of a language that has some type which allows some bit … 查看更多內容

Many type systems have been created that are specialized for use in certain environments with certain types of data, or for out-of-band static program analysis. Frequently, these are based on ideas from formal type theory and are only available as part of prototype research systems.
The following table gives an overview over type theoretic concepts that are used in specialized type systems. The names M, N, O range over terms and the names range over types. The followi…Wikipedia · CC-BY-SA 授權下的文字- 預估閱讀時間: 9 分鐘

https://zh.wikipedia.org/wiki/類型系統- 定型（typing，又稱型別指派）賦予一組位元某個意義。型別通常和記憶體中的數值或物件（如變數）相聯繫。因為在電腦中，任何數值都是以一組位元簡單組成的，硬體無法區分記憶體位址、指令碼、字元、整數、以及浮點數。型別可以告知程式和程式設計者，應該怎麼對待那些位元。 型別系統提供的主要功能有： 1. 安全性 1. 使用型別可允許編譯器偵測無意義的，或者是可能無效 …
