多维数组的索引 [英] indexing for multidimensional array

问题描述

大家好，

我正在将一些C#代码移植到C ++，但有一点让我有些困惑.代码如下:

Hello all,

I am porting some C# code to C++ and there is a particular bit that has me a bit perplexed. The code is as follows:

byte [,,] data = new byte[d,h,w];
int i=0;

for (int z = 0; z < d; z++)
{
   for (int y = 0; y < h; y++)
   {
     for (int x = 0; x < w; x++)
    {
      data[z,y,x]=bytes[i++];
    }
  }
}

因此，变量bytes包含我从文件中读取的数据.通常，我将按以下方式计算线性指数:

So, the variable bytes contains data that I have read from the file. Normally, I would calculate the linear index as follows:

index = (z*h+y)*w+x;

但是，在这种情况下，这似乎不是正确的选择.我想知道是否有人知道我做错了什么明显的事情...

谢谢，

Keith

However, this seems to be not be the right thing in this case. I was wondering if someone knows if I am doing something obviously wrong...

Thanks,

Keith

推荐答案

我认为您正在谈论将C#功能迁移到C ++的挑战.如果这样的话，您可以围绕字节编写方法.

I think you are talking about the challenges to migrate C# features into C++. If itz so, you can write work around method for bytes.
