顺时针打印数组，美丽版

今天看到一段代码，顺时针打印数组。写得太美了，简洁明了，几乎不用任何注释。

转过来，原来是java版的，我改成了C++版。

 

 1     void PrintMatrixClockWise()
 2     {
 3         int m = 5;
 4         int n = 4;
 5         int val[4][5] = 
 6         {    
 7             {1,    2,    3,    4,    5 },
 8             {6,    7,    8,    9,    1 },
 9             {11,   12,   13,   14,   15},
10             {16,   17,   18,   19,   20}
11         };
12 
13         int colMin = 0;
14         int colMax = m;
15         int rowMin = 0;
16         int rowMax = n;
17 
18         while(colMin < colMax && rowMin < rowMax)
19         {
20             for(int i = colMin; i < colMax; i++)
21                 cout << (val[rowMin][i]) << " ";
22             cout << endl;
23             rowMin++;
24 
25             for(int i = rowMin; i < rowMax; i++)
26                 cout << (val[i][colMax-1]) << " ";
27             cout << endl;
28             colMax--;
29 
30             for(int i = colMax-1; i >= colMin; i--)
31                 cout << (val[rowMax-1][i]) << " ";
32             cout << endl;
33             rowMax--;
34 
35             for(int i = rowMax-1; i >= rowMin; i--)
36                 cout << (val[i][colMin]) << " ";
37             cout << endl;
38             colMin++;
39         }
40     }
