C++ int }book; book_id; Accessing Structure Members To access any member of a structure, we use the member access operator (.). The member access operator is coded as a period between the structure variable name and the structure member that we wish to access. You would use struct keyword to define variables of structure type. Following is the example to explain usage of structure: #include #include using namespace std; struct Books { char title[50]; char author[50]; char subject[100]; int book_id; }; int main( ) { struct Books Book1; struct Books Book2; // Declare Book1 of type Book // Declare Book2 of type Book // book 1 specification strcpy( Book1.title, "Learn C++ Programming"); strcpy( Book1.author, "Chand Miyan"); strcpy( Book1.subject, "C++ Programming"); Book1.book_id = 6495407; // book 2 specification strcpy( Book2.title, "Telecom Billing"); 150
C++ strcpy( Book2.author, "Yakit Singha"); strcpy( Book2.subject, "Telecom"); Book2.book_id = 6495700; // Print Book1 info cout
