  2. Duff's device - Wikipedia

    en.wikipedia.org/wiki/Duff's_device

    In the C programming language, Duff's device is a way of manually implementing loop unrolling by interleaving two syntactic constructs of C: the do-while loop and a switch statement. Its discovery is credited to Tom Duff in November 1983, when Duff was working for Lucasfilm and used it to speed up a real-time animation program.

  3. 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 ...

  4. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    Infinite loops can be implemented using other control flow constructs. Most commonly, in unstructured programming this is jump back up (goto), while in structured programming this is an indefinite loop (while loop) set to never end, either by omitting the condition or explicitly setting it to true, as while (true) .... Some languages have ...

  5. Structured programming - Wikipedia

    en.wikipedia.org/wiki/Structured_programming

    At the level of loops, this is a break statement (terminate the loop) or continue statement (terminate the current iteration, proceed with next iteration). In structured programming, these can be replicated by adding additional branches or tests, but for returns from nested code this can add significant complexity.

  6. 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.

  7. Loop dependence analysis - Wikipedia

    en.wikipedia.org/wiki/Loop_dependence_analysis

    In this example, the constraints on control flow are illustrated. Code block 1 shows the correct ordering when using an if statement in the C programming language. Code block 2 illustrates a problem where a statement that is supposed to be controlled by the if statement is no longer controlled by it.

    Source code is written in one or more programming languages. The purpose of programming is to find a sequence of instructions that will automate performing a specific task or solving a given problem.

  9. SICP has been influential in computer science education, and several later books have been inspired by its style.
