int var = 10;int *a;a = &var;所以，&var是var也就是整数10的地址，a用来储存var的地址，当然和&var相等。int a,给a分配了内存空间，使得a可以用来储存var的地址，而a就等于var的值得，等于10。也就是说，*a是用来查看a地址所指向的值。总之，a和&var就是var的地址；*a和var就是var的值，等于10。...

我们定义一个结构体，通常用struct，例如：struct student{int a;int b;char c;}stu;在结构体外定义一个变量的时候，通常是struct student stu1;而你也可以：typedef struct student{int a;int b;char c;}stu;此时在结构体外定义结构体变量就不需要struct了，直接stu stu1;也就是说，typedef给予了stu等价于struct student的权限，使得在结构体外定义变量
