  2. While loop - Wikipedia

    en.wikipedia.org/wiki/While_loop

    Dim counter As Integer = 5 ' init variable and set value Dim factorial As Integer = 1 ' initialize factorial variable Do While counter > 0 factorial = factorial * counter counter = counter-1 Loop ' program goes here, until counter = 0 'Debug.Print factorial ' Console.WriteLine(factorial) in Visual Basic .NET

  3. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    a Count-controlled looping is effected by iteration across an integer interval; early exit by including an additional condition for exit. a Eiffel supports a reserved word retry, however it is used in exception handling, not loop control. a Requires Java Modeling Language (JML) behavioral interface specification language.

For i = first To last «Step 1» instructions Next i. For Each item In set

  5. Conditional loop - Wikipedia

    en.wikipedia.org/wiki/Conditional_loop

    However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language, but many share the same basic structure and/or concept. The While loop and the For loop are the two most common types of conditional loops in most programming languages.

  6. Do while loop - Wikipedia

    en.wikipedia.org/wiki/Do_while_loop

    Do while loops check the condition after the block of code is executed. This control structure can be known as a post-test loop. This means the do-while loop is an exit-condition loop. However a while loop will test the condition before the code within the block is executed.

  7. Statement (computer science) - Wikipedia

    en.wikipedia.org/wiki/Statement_(computer_science)

    condition-controlled loop with test at start of loop: Algol 60: for index := expression while test do <statement> ; Pascal: while test do < statement >; C, Java: while (test) < statement >; Ada: while test loop < sequence > end loop; Fortran 90:

  8. LOOP (programming language) - Wikipedia

    en.wikipedia.org/wiki/LOOP_(programming_language)

    LOOP is a simple register language that precisely captures the primitive recursive functions. [1] The language is derived from the counter-machine model.Like the counter machines the LOOP language comprises a set of one or more unbounded registers, each of which can hold a single non-negative integer.

  9. Control-flow graph - Wikipedia

    en.wikipedia.org/wiki/Control-flow_graph

    Some CFG examples: (a) an if-then-else (b) a while loop (c) a natural loop with two exits, e.g. while with an if...break in the middle; non-structured but reducible (d) an irreducible CFG: a loop with two entry points, e.g. goto into a while or for loop A control-flow graph used by the Rust compiler to perform codegen.
