Go to your local library, mine has tons of programming books.

The one down the block from me has a pretty poor selection of programming books, but the one on the rich side of town has tons of em.

You shouldn't use "true" in C, it's not standard.  TRUE is better. 

Of course that's C++.

MyndFyre, I'm sure you're well aware that you need to create an eBook class. =)

Which I already had, otherwise I would have had a plethora of other errors during compilation.

Code Select Expand


int main(void);
bool like(const book* );

class book {
public:
void buy(void) { }
void trash(void) { }
};

bool like(const book* pbook) {
return true;
}

int main()
{
book eBook;

if ( like(&eBook) == true ) {
eBook.buy;
} else {
eBook.trash;
}

return 0;
}


(There is some other stuff there, because whenever I have to compile C/++ for forum posting I check it.

You not only checked it on a different operating system, you checked it on a different compiler.  If you want to check somebody's code, you ought to at least use the same technology they're using :-P

I'll refer you to ISO/IEC 9899:TC2 section 6.5.2.2: Function Calls.  Specifically:

1 The expression that denotes the called function⁷⁸⁾ shall have type pointer to function
returning void or returning an object type other than an array type.

(Subscript 78):

Most often, this is the result of converting an identifier that is a function designator.

Also:

A postfix expression followed by parentheses () containing a possibly empty, comma-separated
list of expressions is a function call. The postfix expression denotes the called
function. The list of expressions specifies the arguments to the function.

Joe's semantics would simply be a statement of a function-pointer expression, not an actual call to the function.  In any C you need to affix the postfix operator () to make it a valid function call.

You're right, it IS wrong if you assume those are functions, but I meant in general :-P

I assumed those were variables, in which case, I don't think it'll have any warnings.  Of course, it won't do anything either..

That would be silly; buy and trash are verbs.  They should be functions.  :P

Its neither C nor C++. Its pseudo-C. You lose.

On a side note, I'd prefer a physical book too, asuming I had a million dollars (those things are not cheap, and I am broke), and a rocket (it takes a while to get to the store, whereas I can download a book in about a half hour (for big ones)).

What, do you live in a city of 5 people that doesn't have a bookstore?  No wonder you use dial-up.

Buy them used... they're just books and Amazon owns any walk-in bookstore.

I also perfer physical books, I find myself keeping my attention more easily when I'm reading something that's inked on paper as opposed to illuminated on my screen. :)

Not to mention it's MUCH easier on the eyes, and you can sit with your legs kicked back and a lemonade in your other hand.

You don't have a desk..? I eat, sleep, and shower @ my computer.

My neck gets sore if I'm in any of my office chairs for a long time (read: more than an hour or two).  I like having a recliner. 

Books aren't realy that expensive.  I've never paid more than cad$100 for a good one, including shipping.

Note to us: that's ~USD$84

Note to the majority of this forum: We don't make good money working with our government to think $84 is nothing.
