  2. Infinite loop - Wikipedia

    en.wikipedia.org/wiki/Infinite_loop

    This makes part of the data structure into a ring, causing naive code to loop forever. While most infinite loops can be found by close inspection of the code, there is no general method to determine whether a given program will ever halt or will run forever; this is the undecidability of the halting problem.

  3. While loop - Wikipedia

    en.wikipedia.org/wiki/While_loop

    In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement .

  4. Pseudocode - Wikipedia

    en.wikipedia.org/wiki/Pseudocode

    In computer science, pseudocode is a description of the steps in an algorithm using a mix of conventions of programming languages (like assignment operator, conditional operator, loop) with informal, usually self-explanatory, notation of actions and conditions.

  5. Do while loop - Wikipedia

    en.wikipedia.org/wiki/Do_while_loop

    In many computer programming languages, a do while loop is a control flow statement that executes a block of code and then either repeats the block or exits the loop depending on a given boolean condition. The do while construct consists of a process symbol and a condition. First the code within the block is executed.

  6. 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 ...

  7. 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.

  8. Operator-precedence parser - Wikipedia

    en.wikipedia.org/wiki/Operator-precedence_parser

    the outer while loop is entered. op is * (precedence 2) and the input is advanced; rhs is 4; the next token is +, with precedence 1. the inner while loop is not entered. lhs is assigned 3*4 = 12; the next token is +, with precedence 1. the outer while loop is left. 12 is returned. the lookahead token is +, with precedence 1. the inner while ...

  9. Sentinel value - Wikipedia

    en.wikipedia.org/wiki/Sentinel_value

    In computer programming, a sentinel value (also referred to as a flag value, trip value, rogue value, signal value, or dummy data) is a special value in the context of an algorithm which uses its presence as a condition of termination, typically in a loop or recursive algorithm.
