Int b;
} stu. What's the difference

Behind the struct is structure label, it is can omit the
Typedef struct {
int a;
Int b;
} stu. - & gt; Stu is a structure type
Stu ABC; - & gt; ABC is the structure variable name

Struct {int a;
Int b;
} stu. - & gt; Stu is a structure variable name
The type of
Struct {int a;
Int b;
};

CodePudding user response:

Do not recommend such a definition, structure should not be read

CodePudding user response:

Typedef struct {
int a;
Int b;
} stu ;//is a custom type, red part is the original type (is an anonymous structure), the blue part is the new type (a type name), a new type (name) is equivalent to the original type (structure)

struct {
int a;
Int b;
} stu ;//is variable declarations, red variable type (anonymous structure, which is not the structure of the name), the blue part is a variable
