What is the index number of the last element of an array with 9 elements?
(array.length - 1) will find the index of the last element in an array (or -1 if the array is empty).
Full defecation of array?
Full representation of an array begins from the index 0 and ends at n-1 where n is the number of variables of the array.
What are the main features of arrays. How are arrays used and created?
AnswerWhat is an array: In programming languages, an array is a way of storing several items (such as integers). These items must have the same type (only integers, only strings, ...) because an array can't store different items. Every item in an array has a number so the programmer can get the item by using that number. This number is called the index. In some programming languages, the first item has index 0, the second item has index 1 and so on. But in some languages, the first item has index 1 (and then 2, 3, ...).
Index of an element in array?
An array is a group of related elements, with a common variable name. The index is a number that indicates the position of an element within an array: the 1st. element, the 2nd. element, etc. (many languages start counting at zero).
How do you declare an array on Pascal?
type array-identifier = array[index-type] of element-type; array-identifier : the name of your array index-type : any scaler except real element-type : the type of element The index type defines the range of indices and thus the number of elements to allocate. For example, [0..41] will allocate 42 elements indexed from 0 to 41, thus creating a zero-based array. If you require a one-based array, use [1..42] instead. Regardless of the range of indices, the first element is always at the lowest address of the array (the compiler will convert your index range into a zero-based range automatically). The element-type determines the length of each element in the array. Multiplying the element length by the number of elements gives the total amount of memory allocated to the array.
