Thread: Access violation??

Error is this :

C:\Program Files\PellesC\Projects\Tekrar denemeler\dene\dene.c(26): fatal error: Internal error: 'Access violation' at 0x00483798.

Code:

#include <stdio.h>
#include <string.h>

int main()
{
	
	typedef struct string {
	char bir[41];
	char iki[41];
	int section;
} ara;
	FILE *fp;
	fp=fopen("liste.txt","r");
      char a[41];
	int x=0;
	while((fgets(a,40,fp))!=NULL) {
       x+=1;
}
	int b=0;
	rewind(fp);
	ara kayit[x];
	int i=-1;
	for(b=0;b<x;b++) {
          if((b % 3)==0) {
			i++;
			kayit[i].section=(b/3)+1; 
		 fgets(kayit[i].bir,40,fp); }
		if((b % 3)==1) {
			fgets(kayit[i].iki,40,fp); }
	}
for(i=0;i<((x+1)/3);i++) {
		printf("Section %d\n%s\n%s\n",kayit[i].section,kayit[i].bir,kayit[i].iki);
	}
return 0;
}

What the program does is not important , I just want to know what is my fault here as a fault error?

First of all you need a proper code indendation. It very hard to debug the code if it like that. And more ober have you got the liste.txt in the same directory of where the .c file is lcated. Check the return value of the fopen.

And one more thing. The 'i' should be incremented within the loop not in the if statment. If that make sense. And this should be

Code:

int i=-1;

to

Code:

int i=0;

ssharish

First of all , yes I have liste. I told you algorithm is not important coz I did not show you the liste.

Second of all , to increment i in the if statemtnt is the key of the algorithm.

I do not need to chect fopen. Because it always opens it . So I dont bother to control it. Besides , if the problem was that , program would crash after compiling.

This is the liste.txt :

I can't be bothered to read through all that unindented code atm, but heres a random guess thats probably wrong.

Here:

Code:

fp=fopen("liste.txt","r");

Is the file called liste.txt, not list.txt? If theres an error with the filename or the file dosent exist, you will get a memory access violation.

[edit]Looks like i got here a bit late...[/edit]

That is something the compiler says. And I am sorry for all other responses. All are wrong. Do not underestimate people like i=-1 wil give a segment error. If you dont bother to read the i=-1 line , I think you could read the bottom lines which includes a i++ line. And for the first time the loop works , that if statement will definitely true.Anyway. Matsp , I am listening to you, what could cause that ?

The word underestimate may seem like a little setrimental. But man you nearly all write for just to write. I am sorry , but thanks for responses. I know you have good intentions.

i don't mean any offense here, but don't expect people to look thoroughly through you code if you can't even be bothered to indent it correctly.
