PHP has hundreds of base functions and thousands more from extensions. Prior to PHP version 5.3.0, functions are not first-class functions and can only be referenced by their name, whereas PHP 5.3.0 introduces closures. [35] User-defined functions can be created at any time and without being prototyped. [35]
A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as IF, FOR, and GOTO labels. The term "batch" is from batch processing, meaning "non-interactive execution", though a batch file might not process a batch of multiple data.
Jackson's aim was to make COBOL batch file processing programs easier to modify and maintain, but the method can be used to design programs for any programming language that has structured control constructs— sequence, iteration, and selection ("if/then/else").
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.
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 ...
BASIC, Batch files, Visual Basic:: Batch files, COMMAND.COM, cmd.exe: NB. J; from the (historically) common abbreviation Nota bene, the Latin for "note well". ⍝ APL; the mnemonic is that the glyph (jot overstruck with shoe-down) resembles a desk lamp, and hence "illuminates" the foregoing. #
In computer architecture, a branch predictor [1] [2] [3] [4] [5] is a digital circuit that tries to guess which way a branch (e.g., an if–then–else structure ...
The following is a C-style While loop.It continues looping while x does not equal 3, or in other words it only stops looping when x equals 3.However, since x is initialized to 0 and the value of x is never changed in the loop, the loop will never end (infinite loop).
