too many initializers for struct and array

Question

Can someone help me?

Two errors that I couldn't solve:

• too many initializers and
• type(s) preceding 'date'

---

This is a header file book.h

struct date
{

    int date;  >>>>the type(s preceding'date'),don't know what is this??

    int month;

    int year;
};

typedef struct {

    char book_name[51];

    char book_ID[7];

    char author[31];

    char publisher[31];

    struct date book_date;

    double price;


}BOOK;

---

This is a .cpp file

void main()

{

    int i;

    BOOK bk_detail[10] ={

        {"Harry Potter","B1001","JK ROWLING","Little Brown",{30,6,1997},56.00},

        {"Me Before You","B1002","Jojo Moyer","Penguin Group",{3,6,2004},58.00},

        {"Game Of Throne","B1003","George RR Martin","Snow Dany",{4,4,1990},69.00},

        {"Maze Runner","B1004","James Dashner","Chicken Mouse",{3,3,2003},55.00},

        {"Papertown","B1005","John Green","Dutton Penguin",{16,8,2008},47.00},

        {"Twilight","B1006","Stephenie Meyer","Little Brown",{12,7,2005},56.00},

        {"The Hunger Game","B1007","Suzanne Collins","Scholastic Corporation",{3,9,2006},69.00},

        {"No Man Sky","B1008","Nathan Stuart","Littlefinger Group",{4,8,2014},55.00},

        {"Resist the Temptation","B1009","Jon Snow","The Night Watch",{8,9,1998},69.00},

        {"To Code","B1010","Daenerys Targaryen","Dragons BB",{5,3,1997},56.00}

    }; 
    FILE*books_detail=fopen("book_detail.bin","wb");
    if (books_detail == NULL)
    {
        printf("ERROR...\n");
        exit(-1);
    }

    fwrite(&bk_detail,sizeof(bk_detail[0]),10,books_detail);

    fclose(books_detail);

}

I've followed the tutorial steps but it appears that it still have errors,why that's still have these two error.(PS, I'm new to coding.)

Answer 1

The second error is a consequence of the first. The first error, is that given:

 struct date {

a member called date is a constructor - and constructors can't be preceeded by a type. To put it another way, you can't have a member variable with the same name as the struct or class.

The fix is to change it to:

      int day_of_month;

Edit : Except that cpp.sh is entirely happy with:

// Example program

struct Foo
{
    int Foo;
};

int main()
{
    Foo foo;
    foo.Foo = 1;

    return foo.Foo;
}

(which has the same "problem").

I would strongly recommend that rather than using arrays of char , you use std::string throughout. It makes a lot of code much simpler.

Answer 2

The issue is that your struct is named "date" and it has a member variable named "date". The compiler throws an error because they are named the same.

An easy way to think about this is if you made a type of

int int;

Since int is a type, you cannot name variable the same name as a type.
