  2. Structured programming - Wikipedia

    en.wikipedia.org/wiki/Structured_programming

    Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making specific disciplined use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.

  3. Repetition code - Wikipedia

    en.wikipedia.org/wiki/Repetition_code

    In coding theory, the repetition code is one of the most basic linear error-correcting codes. In order to transmit a message over a noisy channel that may corrupt the transmission in a few places, the idea of the repetition code is to just repeat the message several times. The hope is that the channel corrupts only a minority of these repetitions.

  4. Don't repeat yourself - Wikipedia

    en.wikipedia.org/wiki/Don't_repeat_yourself

    "Don't repeat yourself" (DRY), also known as "duplication is evil", is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place.

  5. Iteration - Wikipedia

    en.wikipedia.org/wiki/Iteration

    Some types of programming languages, known as functional programming languages, are designed such that they do not set up a block of statements for explicit repetition, as with the for loop. Instead, those programming languages exclusively use recursion. Rather than call out a block of code to be repeated a pre-defined number of times, the ...

  6. While loop - Wikipedia

    en.wikipedia.org/wiki/While_loop

    first checks whether x is less than 5, which it is, so then the {loop body} is entered, where the printf function is run and x is incremented by 1. After completing all the statements in the loop body, the condition, (x < 5), is checked again, and the loop is executed again, this process repeating until the variable x has the value 5.

  7. Hamming code - Wikipedia

    en.wikipedia.org/wiki/Hamming_code

    The repetition example would be (3,1), following the same logic. The code rate is the second number divided by the first, for our repetition example, 1/3. Hamming also noticed the problems with flipping two or more bits, and described this as the "distance" (it is now called the Hamming distance, after him). Parity has a distance of 2, so one ...

  8. Goto - Wikipedia

    en.wikipedia.org/wiki/Goto

    "GOTO" key on the 1982 ZX Spectrum home computer, implemented with native BASIC (one-key command entry).. Goto is a statement found in many computer programming languages.It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control.

  9. List of data structures - Wikipedia

    en.wikipedia.org/wiki/List_of_data_structures

    This order is usually determined by the order in which the elements are added to the structure, but the elements can be rearranged in some contexts, such as sorting a list. For a structure that isn't ordered, on the other hand, no assumptions can be made about the ordering of the elements (although a physical implementation of these data types ...
