Editing Index notation (section)

==In computing==
In several programming languages, index notation is a way of addressing elements of an array. This method is used since it is closest to how it is implemented in [[assembly language]] whereby the address of the first element is used as a base, and a multiple (the index) of the element size is used to address inside the array.

For example, if an array of integers is stored in a region of the computer's memory starting at the memory cell with address 3000 (the [[base address]]), and each integer occupies four cells (bytes), then the elements of this array are at memory locations 0x3000, 0x3004, 0x3008, …, 0x3000 + 4(''n'' − 1) (note the [[zero-based numbering]]). In general, the address of the ''i''th element of an array with [[base address]] ''b'' and element size ''s'' is {{nowrap|''b'' + ''is''}}.
