What's the difference between writing int frozen() and int frozen(void)?

What's the difference between writing int frozen() and int?
One is a function declaration and the other is just a datatype.

Okay, one more thing;

#include <stdio.h> #include <stdlib.h> struct foo { char fooc[20]; int fooi; }; main() { foo *bar; bar = (struct foo *) malloc(sizeof(foo)); bar->fooi = 16; bar->fooc = "ANUX"; }

Why doesn't the bar->fooc assignment work? Sorry, I'm new to C.

FAQ THAT FAQ. They use non-standard faggot quotes. Hardly a document of any worth.

How are they ``nonstandard''?

main() vs main(void)
Seriously.

Have you read your The M4 macro processor today?

Lurk more.

Your argument boils down to the fact that you suck at LISP and/or don't understand how computers work?

Look, there's no conflict between C and Lisp. If you want attention that badly, find a real issue to argue about.

They're nonstandard because they are not valid English quotes.

>>12
No, I do not read documents that contain faggot quotes, as they are nonstandard, unscientific, and ultimately destructive.

Is that even relevant to the topic, or is it just your way to say ``I haven't read SICP''?

if you declare a function as
int frozen();
then you can do call it with
frozen("faggot", 32, stdout);
which you can't do if you declare it as
int frozen(void);
now fuck off.

That makes no sense. Is this really what you can do in C? Holy shit.

Why would you be able to call a function with parameters when the declaration has none?

Another question;
I want the program to print lines of text, one at the time, after pressing enter. I thought of putting some moot scanfs between the printfs. Is there a better way to do this?

int frozen(); doesn't mean it has no parameters, just as frozen(void); doesn't mean it has no return type.

>>15
No, you put direct quotations in quotes, e.g. "Is that your way of saying 'I haven't read SICP'?"

This makes it a valid quotation.

Putting 0 parameters in a declaration means the number of parameters is unknown

Also, don't cast pointers in C.

Casting pointers is part of the power of C, but it's something that should be done rarely. Casting the return value of malloc() is bad, and a simple google will show the dozens of reasons for it.
