二维数组 [英] two dimensional arrays

问题描述

我有简单的问题PLZ解决。我想打印以下输出。在2d阵列。

1 8 9 16

2 7 10 15

3 6 11 14

4 5 12 13

我将感激你2。

您可以采用4x4二维数组并以[0] [ 0] = 1 ..... a [4] [4] = 13。你试过一些代码吗？我可以帮助你完成该代码。我无法根据本论坛的规则编写完整的代码。


问候

基本上你在这个矩阵中徘徊;每当你打到''墙''时你就会改变y方向
。单个循环和一些if语句可以完成这项工作：

展开 | 选择 | Wrap | 行号

另外，请注意你的2D阵列以这种方式存在于记忆中：


1 8 9 16 2 7 10 15 3 6 11 14 4 5 12 13


你可以将它视为一维数组，每行只显示4个数字。


C ++实际上只有一维数组。 int [4]数组有4个元素，其中每个元素都是int。 int [4] [4]仍然是一个包含4个元素的数组，但是每个元素都是一个4 int的数组。


数组在内存中连续作为元素0 1 2 3。 / BLOCKQUOTE>

Hi,

You can take 4x4 two dimensional array and insert values in such a manner that a[0][0]=1 .....a[4][4]=13. Have you tried some code?. As I can help you in that code. I cannot write full code according the rule of this forum.

Regards

Basically you''re zig-zagging through that matrix; every time you hit a ''wall'' you
change the y-direction. A single loop and a few if-statements can do the job:

Expand|Select|Wrap|Line Numbers

Also, be aware that your 2D array is in memory this way:

1 8 9 16 2 7 10 15 3 6 11 14 4 5 12 13

You could treat it as a 1D array and just display 4 numbers per line.

C++ really only has 1D arrays. An int [4] array has 4 elements where each element is an int. An int [4][4] is still an array of 4 elements but each element is an array of 4 int.

Arrays are in memory contiguously as element 0 1 2 3.
