conditional expression ^a A single instruction can be written on the same line following the colon. Multiple instructions are grouped together in a block which starts on a newline (The indentation is required).
Inline vs. prologue – an inline comment follows code on the same line and a prologue comment precedes program code to which it pertains; line or block comments can be used as either inline or prologue; Support for API documentation generation which is outside a language definition
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
In computer programming, conditional loops or repetitive control structures are a way for computer programs to repeat one or more various steps depending on conditions set either by the programmer initially or real-time by the actual program. A conditional loop has the potential to become an infinite loop when nothing in the loop's body can ...
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
In some languages and programming environments, the use of a case or switch statement is considered superior to an equivalent series of if else if statements because it is: Easier to debug (e.g. setting breakpoints on code vs. a call table, if the debugger has no conditional breakpoint capability) Easier for a person to read
Based on an earlier PTIME algorithm for nominal unification, alphaProlog is a Prolog-like logic programming language with facilities for binding names in terms, which was intended to be useful for programs acting on program syntax (Cheney 2004). Nominal term embeddings may be seen as alternatives to de Bruijn encodings and higher-order abstract ...
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.
