Define a type

[dushantha12]

Hi,

I want to create a struct and use it in my program.In this case I want create this struct as a type. In my code I did create a "config.h" file. And my struct is in this file.

#ifndef LAST_TICKET
typedef struct {
        char routeName[10];
        char sePointOne[32];
	char sePointTwo[32];	
	char strtPoint[32];
	char endPoint[32];
	int fullTotal;
	int halfTotal;
	int lugeTotal;
	int payMethod;
	int cardNumber;
	int currentTripUpDownStatus;
	int currSecIndex;
	int destSecIndex;
	int ticketNumber;
	int tripNumber;
	double pasengerAmount;
	double fullAmount;
	double halfAmount;
	double lugeAmount;	
	double total;
	double balance;	
}LAST_TICKET;
#endif 

All configurations are inside of this file. The problem is If I call this file as "#include "config.h"" after that I can't call again this file any ware in my application. A am new to c and I want to do create a struct as a type and use it any ware in an application.

Thank you.

The problem is If I call this file as "#include "config.h"" after that I can't call again this file any ware in my application.

You should still be able to use the struct like this in a .cpp file for example:

LAST_TICKET.balance = 1000.0;

Does this work for you?

Hi,


TheIdeasMan, thanks for reply. Actually it's working. I mean This. Suppose, I have config.h,a.c and b.c files. Now I have two typdef struct's in config.h for a.c file and b.c file. There are no relation between a.c and b.c. If I do include config.h in a.c it's working for a.c but not foe b.c. If I do include config.h in b.c it's working for b.c but not foe a.c. So now what I want to do.

Thanks.

Wrong.
In your case this is true because you didn't write the header guards correctly.

#ifndef LAST_TICKET
#define LAST_TICKET

// typedef struct ...

#endif 

Many people like giving header guards the name of the file:

#ifndef CONFIG_H
#define CONFIG_H

#endif 

Last but not least, many compilers support #pragma once which replaces the header guards completely.

#pragma once

// typedef struct ...
