structural equivalence vs name equivalence - Stack Overflow
There are two standard ways to determine whether two types are considered the same: name equivalence and structural equivalence. Name equivalence is the most straightforward: two types are equal if, and only if, they have the same name. Thus, for example, in the code (using C syntax) typedef struct {. int data[100];Code sample

WEBAlgol-68, Modula-3, C, ML use structural type equivalence. name equivalence | each type declaration introduces a new type, distinct from all others. Types T1 and T2 are not equivalent. Java and Ada use name equivalence.
WEBWhen are two types equivalent? tF : identical syntactic form (structural equivalence) C, Java, Pascal: name equivalence (name is part of type identity) C: struct foo { int a, b; } struct bar { int a, b; } ≅ typedef struct foo Foo; Foo struct foo ≅ Binding a type to a name also brands it with unique identity.
Type Equivalence - Western University
WEBThe main difficulty arises from the fact that most modern languages allow the naming of user-defined types. For instance, in C and C++ this is achieved by the typedef statement. When checking equivalence of named types, we have two possibilities. Name equivalence. Treat named types as basic types.
WEBTypes are equivalent which have the same name or are formed by the same type expression. x and y are of same type, w , z,v are of same type, but x and w
WEBProgramming languages do not require type equivalence but strive. for defining type compatibility. Two types are compatible if: 1. The two types are equivalent. 2. One is a subtype of the other.

WEBType Equivalence in Classes. In C, C++ and Java, instances of the same struct or class are type-equivalent, and mutually assignable. For example: class MyClass { ... } MyClass v1, v2; v1 = v2;// Assignment is OK. We expect to be able to assign values of the same type, including class objects.

WEBdeclaration equivalence-- two types are equivalent if they lead back to the same type. Example: TYPE T1 = ARRAY [0..10] OF CHAR; TYPE T2 = T1; TYPE T3 = T2; TYPE T4 = ARRAY [0..10] OF CHAR; Types T1, T2, T3 are equivalent. Pascal, Modula-2 use declaration equivalence.

WEBType equivalence When do two types match during type checking? There are two major kinds of matching: name equivalence (two values are of the same type only if they are explicitly declared to be of the same type) and structure equivalence (two values are of the same type only if their types have the same form). The former can be more demanding ...
WEBtype system has: a mechanism to define types and associate them with language constructs. a set of rules for type equivalence, type compatibility, and type inference. Type equivalence details which types are considered the same. Type compatibility states when a value of a certain type can be used in a given context.
WEBType Systems. A type system consists of: 1. A mechanism to define typesand associate them with language constructs. 2. A set of rules for “type equivalence,” “type compatibility,” and “type inference.”. 3. Tuesday, March 30, 2010. …
WEBType Checking (Continued) Type checking relies on type compatibility and type inference rules. Type inference rules are used to infer types of expressions. e.g., type of (a+b)+c is inferred from type of a, b and c and the inference rule for operator ‘+‘. Type inference rules typically operate on a bottom-up fashion.
WEBTwo types are equivalent if they have the same structure. Most languages have mixture, e.g., C: name equivalence for records (structs), structural equivalence for almost everything else.
Lecture 18: April 2, 2008
WEBStructural equivalence: two types are equivalent iff they have the same structure. To test for structural equivalence, a compiler must encode the structure of a type in its representation. A tree (or type graph) is typically used.
WEBWhich notion of Equivalence do Programming Languages Use? C and C++ use structural equivalence except for structs and classes (where name equivalence is used). For arrays, size is ignored. Java uses structural equivalence for scalars. For arrays, it requires name equivalence for the component type, ignoring size. For classes it uses name

Type Checking | Principles of Programming Languages
WEBWe design a type language to specify the expected type of variables and expressions in the language. We extend the syntax of the programming language to allow association of type annotations (in the type language) with variable declarations and procedures.

Prerequisite for type checking: Clarify whether two types are equivalent. Two approaches. Structural equivalence. Same structure means same type. Name equivalence.

WEBIn general, where a value of a given type is usable, any value of an equivalent type may be used in its place . The resolution of type equivalence determines, for example, the compat-ibility of the source and target in assignments and during parameter passing.
c - Name equivalence question - Stack Overflow
WEBBasically, atomic types in a programming language have names and they are used both in name equivalence and structural equivalence. The difference comes from derived types such as int * or char[10] .
Why did the language designers of C do type equivalance like this?
WEBApr 28, 2009 · 25 years ago terms like "name equivalence", "structural equivalence", and "occurence equivalence" were popular. Today type systems are much more formal, and equivalence is typically defined by logical rules rather than informal English.
Comparison of programming languages by type system - Wikipedia
WEBA structural type system means that the language decides whether types are compatible and/or equivalent based on the definition and characteristics of the types. Type checking determines whether and when types are verified.
