{
    union{                 
               int i;
               struct{          
                    char first;
                    char second;
              }half;
            }number;

          number.i=0x4241;        
          printf("%c%c\n", number.half.first, mumber.half.second);

          number.half.first='a';  
          number.half.second='b';
          printf("%x\n", number.i);
}

结果
