[]temp = array[1] array[2]=array[1] array[1]=[]temp
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
A square array has the same number of columns and rows the array [1] is a square array (a trivial example) the array [1 0] [0 1] is a square array the array [1 0 0 0] [0 1 0 0] [0 0 1 0] [0 0 0 1] is a square array the array [1 0 0 0] [0 1 0 0] [0 0 1 0] is not a square array
void bubblesort (int* array, int size) { if (!array size<2) return; int last_swap = size; while (last_swap>0) { int n=last_swap; for (int i=1; i<last_swap; ++i) { if (array[i]<array[i-1]) { array[i]^=array[i-1]^=array[i]^=array[i-1]; n=i; } last_swap = n; } }
By design; it makes the compiler's work easier. 1-based array's addressing-function: Address (array, index) = Address (array) + (index-1)*Elemsize(array) 0-based array's addressing-function: Address (array, index) = Address (array) + index*Elemsize (array)
1. An array of sets. 2. An array that represents a set.
You cannot delete elements from an array. But you can move the elements: if (del_index < no_of_elements-1) { memmove (&array [del_index], &array [del_index+1], sizeof (array [0]) * (no_of_elements - del_index - 1)); } --no_of_elements;
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 ?>
In order to determine which of four number is bigger you need 16 if statements arranged in a nested if statement. That exceeds the complexity of just sorting it in an array. Here is a solution using a simple array sort. int array[] = {7, 2, 27, 4}; int i, swap; do { swap = 0; for (i = 0; i < 4; ++i) { if (array[i]<array[i+1]) { swap=array[i]; array[i]=array[i+1]; array[i+1]=swap; swap=1; } } } while (swap == 1); printf ("%d\n", array[0]);
14-little longer than a standard ruler. 1/4-about thickness of a pen
(array.length - 1) will find the index of the last element in an array (or -1 if the array is empty).
