control structure

<programming> One of the instructions, statements or groups of statements in a programming language which determines the sequence of execution of other instructions or statements (the control flow). In assembly language this typically consists of jumps and conditional jumps along with procedure call and return though some architectures include other constructs such as an instruction which skips the following instruction depending on some condition (PDP?), various kinds of loop instructions (later Motorola 680x0) or conditional execution of all instructions (Advanced RISC Machine). Basic control structures (whatever their names in particular languages) include "if CONDITION then EXPRESSION else EXPRESSION", the switch statement, "while CONDITION do EXPRESSION", "gosub", the suspect "goto" and the much-feared "come from". Other constructs handle errors and exceptions such as traps and interrupts. (1997-09-14)

Control structures in Perl

The basic control structures of Perl are similar to those used in C and Java, but they have been extended in several ways.

Control variable (programming)

In computer programming, a control variable is a program variable that is used to regulate the flow of control of the program.

Control flow

In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.

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.

A set of statements is in turn generally structured as a block, which in addition to grouping, also defines a lexical scope.

Interrupts and signals are low-level mechanisms that can alter the flow of control in a way similar to a subroutine, but usually occur as a response to some external stimulus or event (that can occur asynchronously), rather than execution of an in-line control flow statement.

At the level of machine language or assembly language, control flow instructions usually work by altering the program counter. For some central processing units (CPUs), the only control flow instructions available are conditional or unconditional branch instructions, also termed jumps.

Examples of use of control structures

1. We‘re helping them develop command and control structures.

2. You already see it in the command–and–control structures.

3. We are helping them develop command and control structures.

4. Smart candidates know the old command–and–control structures of politics don‘t work anymore.

5. "The (command and control) structures that are followed by the U.N. are the ones that we have agreed would be adopted by the African Union." "So we say the command and control structures are the UN," he added.
