  2. While loop - Wikipedia

    en.wikipedia.org/wiki/While_loop

    Pascal has two forms of the while loop, while and repeat. While repeats one statement (unless enclosed in a begin-end block) as long as the condition is true. The repeat statement repetitively executes a block of one or more statements through an until statement and continues repeating unless the condition is false. The main difference between ...

  3. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    If xxx1 is omitted, we get a loop with the test at the top (a traditional while loop). If xxx2 is omitted, we get a loop with the test at the bottom, equivalent to a do while loop in many languages. If while is omitted, we get an infinite loop. The construction here can be thought of as a do loop with the while check in the middle. Hence this ...

  4. 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.

  5. 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.

  6. Nassi–Shneiderman diagram - Wikipedia

    en.wikipedia.org/wiki/Nassi–Shneiderman_diagram

    Testing loops: this block allows the program to loop one or a set of processes until a particular condition is fulfilled. The process blocks covered by each loop are subset with a side-bar extending out from the condition. There are two main types of testing loops, test first and test last blocks.

  8. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm , a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.

  9. Structured program theorem - Wikipedia

    en.wikipedia.org/wiki/Structured_program_theorem

    One is the 1946 description of the von Neumann architecture, which explains how a program counter operates in terms of a while loop. Harel notes that the single loop used by the folk version of the structured programming theorem basically just provides operational semantics for the execution of a flowchart on a von Neumann computer.
