array

Question

what is index input and output in .net

Vulpes · Answer

The index of a single dimensional array is the number of an element within the array. The element at that index can be accessed by following the array name with the index enclosed in square brackets. The index ranges from 0 to the length of the array minus 1. So in an array arr with a length of 5 arr[0] denotes the first element and arr[4] denotes the last element. As arrays once created remain fixed in size the index remains the same when you are inputting (setting) an element within the array or outputting (getting) that element from the array.
