 | | With statically typed languages, there usually are pre-defined types for individual pieces of data (such as numbers within a certain range, strings of letters, etc.), and programmatically named values (variables) can have only one fixed type, and allow only certain operations: numbers cannot change into names and vice versa. |
 | | Most mainstream statically typed languages, such as C, C++, C#, Java and Delphi, require all types to be specified explicitly; advocates argue that this makes the program easier to understand, detractors object to the verbosity it produces. |
 | | Strongly typed languages do not permit the usage of values as different types; they are rigorous about detecting incorrect type usage, either at runtime for dynamically typed languages, or at compile time for statically typed languages. |
