在Visual Studio 2017中删除垂直点划线(Remove vertical dotted indentation lines in Visual Studio 2017)

 在内存中， int将连续布局。 如果您不提供除第一个维度之外的所有维度，则无法确定您请求的int的位置。 如果您的矩阵是 
 
 1  2  3  4  5
 6  7  8  9 10
11 12 13 14 15
 
 在内存中它仍然显示为： 
 
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
 
 如果我知道第二维有5个int ，那么matrix[2][1]在地址matrix + (2 * 5) + 1 ，我必须进入5列，两次，到达第三维行，然后将另外一个元素放入该行以获取列。 如果没有第二维的大小，我无法确定值将在内存中出现的位置。 （在这种情况下，“I”表示编译器/运行时） 

In memory, the ints will be laid out contiguously. If you don't provide all but the first dimension, there's no way to figure out the location of the int you are requesting. if your matrix is
 
 1  2  3  4  5
 6  7  8  9 10
11 12 13 14 15
 
In memory it still appears as:
 
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
 
if I know the second dimension has 5 ints in it, then matrix[2][1] is at address matrix + (2 * 5) + 1, I must go in by 5 columns, two times, to get to the third row, then one more element into that row to get the column. Without the size of the second dimension, I have no way of figuring out where the values will appear in memory. (in this case "I" means the compiler/runtime)
