Definition and use of structure (1)

Structure concept:

Custom data types, some types of collections form a type.

Definition and use of structure:

struct structure name {member 1 , member 2 , ... };

There are three ways for a structure to create variables:

1. struct structure name variable name; (recommended)

1      struct Student s1;
 2      s1.name = " Zhang San " ;
 3      s1.age = 18 ;
 4      s1.score = 100 ;    

2. struct structure name variable name = {member 1 , member 2 , ...}; (recommended)

1  struct Student s1 = { " 李四" , 18 , 100 };

3. Create variables by the way when defining structures (not recommended)

1 struct Student
2 {
3     string name;
4     int age;
5     int score;
6 }s3;
