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 ...
Using different keywords for the one-alternative and two-alternative "if" statements. S-algol uses if e do s for the one-alternative case and if e1 then e2 else e3 for the general case. [10] Requiring braces unconditionally, like Swift. This is effectively true in Python as its indentation rules delimit every block, not just those in "if ...
In computing, IIf (an abbreviation for Immediate if [1]) is a function in several editions of the Visual Basic programming language and ColdFusion Markup Language (CFML), and on spreadsheets that returns the second or third parameter based on the evaluation of the first parameter.
Within an imperative programming language, a control flow statement is a statement that results in a choice being made as to which of two or more paths to follow. For non-strict functional languages, functions and language constructs exist to achieve the same result, but they are usually not termed control flow statements.
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.
This allows one of two bodies to be executed. :If condition :Then :body one :Else :body two :End In this case the calculator evaluates condition, if it evaluates to true body one is executed, however, if condition evaluates to false, body two is executed. Unlike many other programming languages, TI-BASIC has no else if construct, or any switch ...
During a period of just over two years, VBScript advanced from version 1.0 to 2.0, and over that time it gained support from Windows system administrators seeking an automation tool more powerful than the batch language first developed in the early 1980s. [6] On August 1, 1996, Internet Explorer was released with features that included VBScript ...
