Structure:

A user-defined, available data type that allows you to store different types of data items.

Definition/declaration:

struct type name {    member 1;    member 2;    .... Member N;} variables;

Instance:

// define struct type first, and then define structure body variable structstudent{Charno[ -];//School Number    Charname[ -];//name      Charsex[5];//Sex    intAge//Age}; structstudent STU1,STU2;//at this point stu1,stu2 is the student struct variable//define struct-body variables while defining struct-typestructstudent{Charid[ -];//School Number    Charname[ -];//name    Charsex[5];//Sex    intAge;//Age} stu1,stu2;structstudent Stu3;//typedefstructstudent{...} STUDENT; STUDENT stu1;

To access struct Members:

Use the member access operator (.) to access the members of the structure .

// Print printf ("STU1 Name:%s\n", stu1.name);

struct pointer:

// Definition/Declaration struct student *pstu1; // Assignment value pstu1 = &stu1; // visit pstu1, name;
