In the C family of languages and ALGOL 68, the word cast typically refers to an explicit type conversion (as opposed to an implicit conversion), causing some ambiguity about whether this is a re-interpretation of a bit-pattern or a real data representation conversion. More important is the multitude of ways and rules that apply to what data ...
This behavior exists to avoid integer overflows in implicit narrowing conversions. For example, in the following code: For example, in the following code: In C23 , the boolean type was moved to bool , making the <stdbool.h> header now useless.
The cast operator is not overloadable, but one can write a conversion operator method which lives in the target class. Conversion methods can define two varieties of operators, implicit and explicit conversion operators. The implicit operator will cast without specifying with the cast operator (()) and the explicit operator requires it to be used.

For example, in ANSI C: int add_one ( int x ) { int result ; /* declare integer result */ result = x + 1 ; return result ; } The signature of this function definition, int add_one(int x) , declares that add_one is a function that takes one argument, an integer , and returns an integer.

This is a comparison of the features of the type systems and type checking of multiple programming languages.. Brief definitions A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.
