In modular programming, specific task functions are often created and used or reused for array processing. Array processing functions are usually passed the array and any data necessary to process the array for the given task.
It should be noted that arrays are passed by reference in most current programming languages. Array processing functions must take care not to alter the array unless intended.
Arrays are an important complex data type used in almost all programming. We continue to concentrate on simple one dimension arrays also called a list. Most programmers develop a series of user-defined specific task functions that can be used with an array for normal processing. These functions are usually passed the array along with the number of elements within the array. Some functions also pass another piece of data needed for that particular function’s task.
This module covers the displaying the array members on the monitor via calling an array function dedicated to that task.
Function Main Declare Integer Array ages Assign ages = [49, 48, 26, 19, 16] Call DisplayArray(ages) End Function DisplayArray (Integer Array array) Declare Integer index For index = 0 to Size(array) - 1 Output array[index] End End
49 48 26 19 16
- array function
- A user-defined specific task function designed to process an array.
