题目大意：POJ2996的反向。输入2996的输出，输出2996的输入。
解题思路：
　　　　1.定义结构体存每个格子的状态
　　　　2.初始化结构体数组为“：：：”||“...”　　　　
　　　　3.读取字符串,根据数据改变结构体的第二个变量
　　　　4.格式输出
Code：
 1 #include<iostream>
 2 #include<string>
 3 using namespace std;
 4 struct Point
 5 {
 6     char a,b,c;
 7 } P[10000];
 8 void Init()
 9 {
10     int ok=1;
11     for (int i=1; i<=64; i++)
12     {
13         if (ok) P[i].a=P[i].b=P[i].c=':';
14         else P[i].a=P[i].b=P[i].c='.';
15         if (i%8) ok=!ok;
16     }
17 }
18 int main()
19 {
20     char x,y;
21     int i,j;
22     string White,Black;
23     string tmp="+---+---+---+---+---+---+---+---+";
24     getline(cin,White);
25     getline(cin,Black);
26     Init();
27     for (i=7; i<=White.length()-1; i++)
28     {
29         if (White[i]>='A'&&White[i]<='Z')
30         {
31             x=White[i+2],y=White[i+1];
32             P[(x-48-1)*8+(y-'a'+1)].b=White[i];
33         }
34         else if (White[i-1]==',')
35         {
36             x=White[i+1],y=White[i];
37             P[(x-48-1)*8+(y-'a'+1)].b='P';
38         }
39     }
40     for (i=7; i<=Black.length()-1; i++)
41     {
42         if (Black[i]>='A'&&Black[i]<='Z')
43         {
44             x=Black[i+2],y=Black[i+1];
45             P[(x-48-1)*8+(y-'a'+1)].b=Black[i]+32;
46         }
47         else if (Black[i-1]==',')
48         {
49             x=Black[i+1],y=Black[i];
50             P[(x-48-1)*8+(y-'a'+1)].b='p';
51         }
52     }
53     cout<<tmp<<endl;
54     for (i=8; i>=1; i--)
55     {
56         cout<<'|';
57         for (j=1; j<=8; j++)
58             cout<<P[(i-1)*8+j].a<<P[(i-1)*8+j].b<<P[(i-1)*8+j].c<<'|';
59         cout<<endl;
60         cout<<tmp<<endl;
61     }
62     return 0;
63 }
