如何声明和在C 4维数组初始化 [英] How to declare and initialize in a 4-dimensional array in C

问题描述

我是比较新的编程，我需要在4维数组进入，我只能勉强换我的头周围。所以，让我们从一个简单的3-D阵列，每个像这样2个元素：

I'm relatively new to programming, and I need to enter in a 4-dimensional array, and I can barely wrap my head around it. So, let's start with a simple 3-d array, 2 elements each like so:

int arr[2][2][2] = 
{
    {
        {1, 2}
        {3, 4}    //redline on "{"
    }
    {             //redline on "{"
        {5, 6}
        {7, 8}
    }
};

VS-2012红线的{3，并说之前的期待}代替。我怎么就能够在一个整洁格式输入阵列？有4个尺寸将使它更复杂，我需要能够清楚地看到的数据。

VS-2012 redlines the "{" before the "3", and says it's expecting a "}" instead. How would I be able to enter the array in a neat format? Having 4 dimensions will make it more complicated, and I need to be able to see the data clearly.

另外，我要在我的阵列好多个零的，在本质论每ARR [N] [N]为0，所以我想知道如果我可以做初始化稍微简单一些。

Also, I'm going to have a good number of zeroes in my array, in essense every arr[n][n] will be 0, so I'm wondering if I can make the initialization a little simpler.

我的数组将是类型

int arr[7][7][15][2]

还是我最好使用结构呢？

Or am I better off using struct instead?

在此先感谢！

有关的三维阵列

 int arr[2][3][4] = { 
                       { 
                          {1, 2, 1, 2}, {1, 2, 1, 4}, {1, 2, 4, 4} 
                       },
                       {  
                          {1, 1, 2, 4}, {1, 2, 1, 4}, {1, 2, 1, 4} 
                       } 
                    };

or int arr[2][3][4] = {1,2,1,2,1,2,1,4,1,2,4,4,1,1,2,4,1,2,1,4,1,2,1,4};
