inta[]={45,4,67,23,65,87,34,52,56};数组中a[5]的值为()
A: 23
B: 45
C: 65
D: 87
A: 23
B: 45
C: 65
D: 87
举一反三
- int a[ ]={45,4,67,23,65,87,34,52,56};数组中a[5]的值为
- 【单选题】What will be the output of the following Python code? a=[13,56,17] a.append([87]) a.extend([45,67]) print(a) A. [13, 56, 17, [87], 45, 67] B. [13, 56, 17, 87, 45, 67] C. [13, 56, 17, 87,[ 45, 67]] D. [13, 56, 17, [87], [45, 67]]
- 下列语句执行后，D的值为（）。A=[1:3,7;4:6,-56;34,23,56,-45;4,2,4,5];D=max([A(3),A(6),A(8),A(11)]) A: 34 B: 5 C: 2 D: 56
- 数组a定义：int[][] a = new int[4][5]；则 a.length 的值为______ ，a[1].length 的值为______ 。
- .以下能对二维数组a进行正确初始化的语句是()。(A)inta[2][]={{1,0,1},{5,2,3}};(B)inta[][3]={{1,2,3},{4,5,6}};(C)inta[2][4]={{1,2,3},{4,5},{6}};(D)inta[][3]={{1,0,1},{},{1,1}}; A: inta[2][]={{1,0,1},{5,2,3}}; B: inta[][3]={{1,2,3},{4,5,6}}; C: inta[2][4]={{1,2,3},{4,5},{6}}; D: inta[][3]={{1,0,1},{},{1,1}};
