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).
What is meant by irregular dimensional array?
An irregular dimensional array is a special type of multi-dimensional array.First we must understand that a multi-dimensional array is just an array of arrays. Each element in the array is, itself, an array of elements.A regular multi-dimensional array will be an array of size n, with each element containing a separate array of size m. That is, each sub-array has the same size.An irregular multi-dimensional array will be a multi-dimensional array in which each sub-array does not contain the same number of elements.Regular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4, 5}array[2] = new array{6, 7, 8}array[3] = new array{9, 10, 11}This regular array is an array of size 4 in which each sub-array is of size 3.Irregular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4}array[2] = new array{5, 6, 7}array[3] = new array{8, 9, 10, 11}This irregular array is an array of size 4 in which the size of each sub-array is not the same.
How do you use subscripts with an array?
An array is a list of several related elements. You use the subscript to specify which element you want to access. For example, in Java you might have an array called myArray, with 10 elements (numbered from 0 to 9); myArray[3] would access the fourth element in the array. A variable may be used instead of a constant.
Differentiate single dimensional array to double dimensional array?
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
Why array is a implicit pointer?
An array of pointers is exactly what it sounds like - one or more pointers arranged in order in memory, accessible through a common base name and indexed as needed. Philosophically, there is no difference between an array of pointers and an array of objects...int a[10]; // 10 integers, named a[0], a[1], a[2], ..., a[9]int *b[10]; // 10 pointers to int, named b[0], b[1], b[2], ..., b[9]If you initialize the array of pointers...int i;for (i = 0; i < 10; i++) b[i] = &a[i];... then *b[0] would be the same as a[0], etc.
Give an example of a multi dimensional array in Cpp?
// 2 dimensional array (a sudoku puzzle): char sudoku[9][9]; // 3 dimensional array (100 sudoku puzzles): char sudokus[100][9][9]
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).

What is a example of a array?
An ordered array is simply an array where all elements are in sorted order: int a[] = {3, 6, 9, 10, 15, 21}; // ordered array An array can either be initialised with ordered elements or the elements may be sorted after initialisation. When inserting new elements into an ordered array, the order must be maintained.
How can you mix up the order of values in a PHP array?
To shuffle an array in PHP is easy to do, all you need to use is the shuffle() function like shown below: <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); shuffle($array); // array results will be randomly shuffled ?>
How do you pick a random value from a PHP array?
To pick random results from an array in PHP you will need to use the array_rand() function, you can select the amount of results you wish it too select too. <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); $rand_results = array_rand($array, 3); // will select 3 random results from the array and store in a new array ?>
How do you access 2D array elements by using single variable?
int main() { int array[3][3]; int i; for(i=0; i <9;i++) { printf("the element is %d\n", array[i/3][i%3]); } return 0; }
How do you merge and sort an array using PHP?
To merge and sort an array in PHP you need to use the array_merge() and sort() functions like shown in the example below: <?php $array1 = array(1, 5, 3, 9, 7); $array2 = array(8, 2, 6, 4, 0); // merge the arrays $merge = array_merge($array1, $array2); // 1, 5, 3, 9, 7, 8, 2, 6, 4, 0 // sort the array sort($merge); // 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ?>

What is the code of sorting out an given unsorted array in text file for c plus plus?
Sorting arrays (of any type) can be achieved with the C++ standard library std::sort function: std::array<int, 5> a {9, 3, 5, 1, 7}; // fixed-length array std::vector<int> b {9, 3, 5, 1, 7}; // variable length array int c[] = {9, 3, 5, 1, 7}; // C-style array std::sort (a.begin(), a.end()); std::sort (b.begin(), b.end()); std::sort (c, c+5);
