I'm getting the error " 'FILE' not declared in this scope" many times while compiling my program, as well as " 'FILE' does not name a type" twice. I think one may be a product of the other.
Here's one line i'm getting the first error on:
(I think that's the right line; compiler says "ISBNPrefix.h:16:18:", and that's line 16.)Code:FILE* open(const char filename[]){
Please advise. Let me know if you need more info; I don't wanna post my code if unnecessary.
Somewhere you need
#include <stdio.h>
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I haveincluded on one .cpp, andCode:#include<iostream> #include<cstring> #include<cstdlib> #include<stdio.h>on the other.Code:#include<string.h> #include<cstring> #include<iostream> #include<cstdlib> #include<stdio.h>
Well we're not going to be able to tell from 1 line of code.
> I think that's the right line; compiler says "ISBNPrefix.h:16:18:", and that's line 16.)
The first 20 lines of this file perhaps.
Why do you have code inside a .h file?
Is stdio.h included BEFORE this file?

Woops, I read 'ISBNPrefix" but didn't think to check whether it was the .h or .cpp; the line I gave before was wrong, then.
ISBNPrefix.h is short, minus comments, so I'll post the whole thing.
>Why do you have code inside a .h file?Code:FILE* open(const char filename[]); int isRegistered(FILE* fp, int area); //With comments in, this one's line 16 int minNoDigits(FILE* fp, int area); int isRegistered(FILE* fp, int area, const char publisher[]); int close(FILE* fp);
I don't, it's only (what's the term for placeholder function definitions, again?)s.
>Is stdio.h included BEFORE this file?
Should it be? That's probably my problem, right there.
Edit: Yeah, it was. Thanks!
