int i,j; p3; 如果将 p1=p2 ,则ok;如果将 p1=p3 ,则编译器提示"incompatible types when assigning to type ‘struct <anonymous>' from type ‘struct <anonymous>'",两者的实际类型是不一样的。 2、显式声明一个结构体 struct node int i,j; ; 声明了一个结构体 struct node,如果需要声明一个它的...

c++ anonymous union,struct -- 匿名联合体和机构体 结构体和联合体各自的基本用法不赘述,仅说一下他们匿名时访问的情况。如果是token不同,可以直接跨层访问。例子 #include <iostream> using namespace std; struct zoo_obj{ string name; union {
struct s { struct { int x; }; // Anonymous struct, no identifier and no tag struct a { int x; }; // NOT Anonymous struct, has an identifier 'a' struct { int x; } b; // NOT Anonymous struct, has a tag 'b' struct c { int x; } C; // NOT Anonymous struct }; struct ...
