大小端之分

我们知道关于字节序有大端和小端之分。一般来说，Inter的处理器使用的是小端（little Indian），Moto的处理器使用的是大端。大端和小端的区别在于，内存对于变量的存放规则不同。小端存储模式是低位放在低地址，高位存放在高地址。而大端则相反。

     简单示例如下：

          a=0x11223344；

                            低                                                             高

     地址由低到高————————————————————>

      小端字节序      44     33    22     11

      大端字节序      11     22    33     44

 那么为了判断存储方式属于大端还是小端存储，我们给出如下代码
