  2. Index notation - Wikipedia

    en.wikipedia.org/wiki/Index_notation

    The second method is used when the number of elements in each row is the same and known at the time the program is written. The programmer declares the array to have, say, three columns by writing e.g. elementtype tablename[][3];. One then refers to a particular element of the array by writing tablename[first index][second index]. The compiler ...

    WriteLine ($"{member} is the member number {index} of the {nameof(doeFamily)}");}} In this example, the indexer is used to get the value at the nth position, and then to get the position in the list referenced by its value.

  4. Index register - Wikipedia

    en.wikipedia.org/wiki/Index_register

    Index register display on an IBM 7094 mainframe from the early 1960s. An index register in a computer's CPU is a processor register (or an assigned memory location) [1] used for pointing to operand addresses during the run of a program. It is useful for stepping through strings and arrays. It can also be used for holding loop iterations and ...

    to mean an offset from the address of a structure rather than from the address of the pointer itself; [citation needed] to mean a pointer containing its own address, which can be useful for reconstructing in any arbitrary region of memory a collection of data structures that point to each other. [13]

  6. For loop - Wikipedia

    en.wikipedia.org/wiki/For_loop

    In computer programming, a loop counter is a control variable that controls the iterations of a loop (a computer programming language construct). It is so named because most uses of this construct result in the variable taking on a range of integer values in some orderly sequences (for example., starting at 0 and ending at 10 in increments of 1)

  7. C syntax - Wikipedia

    en.wikipedia.org/wiki/C_syntax

    A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.

  8. Comparison of programming languages (array) - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_programming...

    The following list contains syntax examples of how to determine the dimensions (index of the first element, the last element or the size in elements). Some languages index from zero. Some index from one. Some carry no such restriction, or even allow indexing by any enumerated type, not only integers.

  9. Portal:Computer programming - Wikipedia

    en.wikipedia.org/wiki/Portal:Computer_programming

    Computer programming is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
