看不懂微软MSDN上关于struct的说明
微软msdn上的struct写法，http://msdn.microsoft.com/en-us/library/64973255(v=VS.90).aspx
没有明白下面代码的意思，谁给解释下

C/C++ code

struct CELL {   // Declare CELL bit field     unsigned short character  : 8;  // 00000000 ????????     unsigned short foreground : 3;  // 00000??? 00000000     unsigned short intensity  : 1;  // 0000?000 00000000     unsigned short background : 3;  // 0???0000 00000000     unsigned short blink      : 1;  // ?0000000 00000000  } screen[25][80];       // Array of bit fields  

[解决办法]
看member-list，然后提示看Class Members，跳到http://msdn.microsoft.com/en-us/library/8802cfa9-705d-4f37-acde-245d6838010c%28v=vs.90%29，看Bit fields，跳到http://msdn.microsoft.com/en-us/library/ewwyfdbe%28v=vs.90%29
