Structs

Syntax:

struct type_name {
    field_type1 field_name1;
    field_type2 field_name2;
    field_type3 field_name3;
    .
    .
} variables_with_this_type;

• type_name :

  • A name for the structure type.

• variables_with_this_type :

  • Optional field.

  • Can be a set of valid identifiers for objects that have the type of this structure.

Defining a struct type, and creating 3 variables with its type separately:

struct product {
    int weight;
    double price;
};

product apple, banana, melon;

Defining a struct type, and creating 3 variables with its type right away:

struct product {
    int weight;
    double price;
} apple, banana, melon;

• Also works:

struct {
    int weight;
    double price;
} apple, banana, melon;

Pointer to a struct:

struct movie_t {
    string title;
    int year;
};

movie_t  my_movie;
movie_t* p_movie;

• Dereferencing a struct to get its value:

  (*p_movie).
  

  p_movie->
