[RESOLVED] Simple C error!

C Code:

#ifndef _readIn_h
#define _readIn_h
 
void readIn(polynomial*, settings*);
 
#endif

polynomial and settings are typedef structs in a header file that readIn.C uses. So i shouldnt have to include the header file in this header file right?

Says it expects ')' before the '*' token... but it is fine and so is all other files... no other errors so i am a little confused!

Without knowing any more about this, it appears to me that you don't have a definition for "polynomial" and "settings" defined anywhere in the scope here. The general form of your prototype seems right but the compiler doesn't recognize the two keywords.

adt.h

C Code:

#include <stdio.h>
#include <stdlib.h>
 
/* ONLY ARRAYS NEED TO BE POINTERS */
 
/* Polynomial Structure */
typedef struct
{
    int degree;
    double* coe;
    double constant;
} polynomial;
 
 
/* Settings Structure */
typedef struct
{
    int upper;
    int lower;
    double iterations;
} settings;
 
 
/* Results Structure */
typedef struct
{
    double stdDev;
    double stdErr;
    int Fi;
    int Fav;
    double solution;
} results;

readin.c

C Code:

#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#include "adt.h"
    
void readIn(polynomial* p, settings* s)
{
      /* reads in all data */
      /* didn't copy it for length reasons */
      /* had no errors though */
}

readin.h

C Code:

#ifndef _readIn_h
#define _readIn_h
 
void readIn(polynomial*, settings*);
 
#endif

These are the related files and code not sure if this helps you?... i might try using a different IDE for this assignment if i can if i cant figure it out by end of today.

Ooooo appears the error was in the main.c file... using Quincy and the formatting of errors is a bit weird thought there was only one... but i had included readIn.h before adt.h and it didn't like that so done...

C Code:

#include "adt.h"
#include "readIn.h"

Fixed :)

Glad we could help! ;-)
