[Programming] C Language Structure and programming structure

Struct

Struct name {} variable name;

Struct variable:

Struct person {

Char * name;

Int age;

Float score;

} Student;

Member acquisition and assignment

// Members of the acquisition and assignment

Student. name = "taoshihan ";

Student. age = 30;

Student. score = 100;

Printf ("name = % s \ n", student. name );

C language struct Array

Struct stu {

Char * name;

Int age;

Float score;

} Classes [5];

Traverse struct Arrays

Struct people {

Char * name;

Int age;

Float score;

} D [] = {

{"Taoshihan", 20,100 },

{"Lisi", 30, 90}

};

Int len = sizeof (d)/sizeof (d [0]);

Printf ("d length = % d \ n", len );

For (int I = 0; I <len; I ++ ){

Printf ("loop... % s, % d, %. 1f \ n ", d [I]. name, d [I]. age, d [I]. score );

}

C language struct and pointer

Struct name * variable name;

Struct person1 {

Char * name;

Int age;

Float score;

} A = {"taoshihan", 20,100}, * B = &;

Struct person1 * c = &;

Get struct members

Printf ("B. name = % s \ n", (* B). name );

Printf ("c. name = % s \ n", c-> name );
