Nettetint [] arr = new int [] {8, 10, 2, 7, 4, 56}; Or even as: int [] arr = {8, 10, 2, 7, 4, 56}; Both the above statements declare an array named arr and store the integers 8, 10, 2, 7, 4 and 56 in it. We can also say that 8, 10, 2, 7, 4 and 56 are the elements of the array. The pictorial view of the array arr is shown below. Nettetarr is the name of array. first dimension represents the block size (total number of 2D arrays). second dimension represents the rows of 2D arrays. third dimension represents the columns of 2D arrays. i.e; int arr [3] [3] [3], so the statement says that we want three such 2D arrays which consists of 3 rows and 3 columns.
Nettet设有如下定义： int arrp []=6, 7, 8, 9, 10; int *ptr; ptr=arr; * (ptr2)=2; printf ("%d, %d\n", *ptr, * (ptr2)); 则下列程序段的输出结果为 ( )。 A．8，10B．6，8C．7，9D．6，2 答案 D [ … Nettet7. jul. 2013 · int *array = new int [n]; It declares a pointer to a dynamic array of type int and size n.
