Hey Guys, I have some code that is driving me insane. I keeps throwing the following error:

main.cpp: In function âint main()â:
main.cpp:12: error: request for member âdispBookâ in âbook1â, which is of non-class type âBook ()()â


and I cant not find out for the life of me why. I beleive I have all my -> correct so that shouldnt be the problem. Here is my code:

lab04.cpp

#include"lab04.h"

Book::Book()
{
        title = "";
        author = "unknown";
        int price = 795;
        genre = 0;
        status = false;
}

Book::Book(string title, int price)
{
        this->title = title;
        this->price = price;
        author = "unknown";
        genre = 0;
        status = false;
}



void Book::dispBook(void) const
    {
    cout.setf(ios::fixed | ios::showpoint);
    cout.precision(2);

    cout << "Title   : \"" << title << "\"\n"
         << "Author  : \"" << author << "\"\n"
         << "Price   : $" << price / 100.0 << endl
         << "Genre   : " << genre
         << "In stock? " << (status ? "yes" : "no")
         << endl;
    return;
    }

main.cpp

#include<iostream>
#include<string>
#include"lab04.h"
using namespace std;

int main()
{
        string title = "The art of Wooting";
        int price = 203;
        Book book1;
        Book book2(title,price);
        book1.dispBook();
        book2.dispBook();

		system("pause");
		return 0;
}

Lab04.h

#ifndef LAB04_H
#define LAB04_H
#include<iostream>
#include<string>
using namespace std;

class Book
{

public:
        Book();
        Book(string,int);
        void dispBook(void) const;
private:
        string title;
        string author;
		int price;
        int genre;
        bool status;
};
#endif

any help is greatly appreciated as im starting to get sore eyes lol Thanks!

You're re declaring/defining price in the no arg constructor [line 7].

[Twoods196]

if your referring too

Book::Book()
{
        title = "";
        author = "unknown";
        int price = 795;
        genre = 0;
        status = false;
}

I had the int price there just as a test. If not, im not sure what u mean

[#define]

It runs ok for me. Maybe try taking void out of dispBook().

[Twoods196]

Thats the thing, it works fine in Visual Studio but our teacher is making us do it in linux with VIM. It gives those errors in there.

[#define]

Did you copy the text files over? Text files are slightly different in Linux and Windows.

[Twoods196]

Yes I copied it over, but I see no diffrence in the 2

This error would normally happen if you do:

Book book1();

This looks like a function declaration to the compiler and so book1 becomes a function pointer, not an object. However, I'm not sure why this should be the case with your current code.
Is this your exact code? Have you edited it in any way?

Try making a brand new project, copy and paste the code and see what happens.

[Twoods196]

Yes its the exact code, an orginally I had the Book book1() and changed it. But it still throws the error

What command are you using to compile? Are you absolutely sure that Book.cpp is being linked with the executable? Since nothing else seems to be the cause of the issue (including line endings), it might be worth a check.

[jimblumberg]

If you comment out line 12 does the program compile? Are you using the command line to compile the program or an IDE. If an IDE which one? If not then show the complete compile command.

The code posted in post #1 compiles fine for me on Linux. So if it still doesn't compile for you, please use the full editor and attach the actual files.
