declared type vs static type

PDF	Type static type dynamic type The static type of a variable is the type of the variable given in its declaration • The dynamic type of a variable is the type of the value in the variable

A statically-typed language is a language (such as Java, C, or C++) where variable types are known at compile time.
In most of these languages, types must be expressly indicated by the programmer; in other cases (such as OCaml), type inference allows the programmer to not indicate their variable types.

What is the difference between static typed and dynamic typed?

In a statically typed language, data types are defined during compile time and cannot change during runtime.
This behavior is because of static type checking.
In contrast, dynamic typing allows variables to change their data type during runtime.

Is static typing better than strong typing?

Strongly typed means that there are restrictions between conversions between types.
Statically typed means that the types are not dynamic - you can not change the type of a variable once it has been created.

What is a static type?

Statically typed is a programming language characteristic in which variable types are explicitly declared and thus are determined at compile time.
This lets the compiler decide whether a given variable can perform the actions requested from it or not.
Static typing associates types with variables, not with values.

First, dynamically-typed languages perform type checking at runtime, while statically typed languages perform type checking at compile time. This means that Autres questions
