拷贝构造函数必须用引用作为参数，否则会造成死循环
 
当传递对象参数时候必然是operator=]]>https://blog.youkuaiyun.com/DevilsAreTremeble/article/details/5805182https://blog.youkuaiyun.com/DevilsAreTremeble/article/details/5805182DevilsAreTremebleWed, 11 Aug 2010 19:51:00 +0800引用在声明的时候必须初始化。这一点类似常量。
int &ra = b;
 
引用做形参的时候极类指针，
int fun(int &a, int *p)
 
指向数组的引用
int （&ra）[N] = arr；
所以当函数传递一个数组引用的时候  
int fun(int(&ra)[N]  );(N必须是常量，ra是形参)；
在该场合下最好用指针

            int (*p)[5] = &a;
            *p = a;  p[0] = a;  P[0][0] = a[0]; p+1 = &a+1 = a[5];
  
指向函数的指针
         void f(int ); 
         void (*p)(int );
         p[0](3);
         *p();

　          ★如果a是byte、short或int型数据，系统总是先计算出n%32的结果m，然后进行a>>m运算。
★对于long型数据，系统总是先计算出n%64的结果m，然后进行a>>m运算。
★比如：
　　　　　　对于int数 5>>1与5>>33的结果相等；
　　　　　　对于long数 5>>1与5>>65的结果相等。
与运算
    用来将某些位数清零
