What is wrong?

[Talos]

Hi

Can someone find out what is wrong? Program reads input from the keyboard and should replace some strings that are found in 'opmaak.txt' I found that the Content of 'Kode' changes when something is put into 'Vervang'
Somebody know what I'm doing wrong?


My code:

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


int main(void)
{
  int intikken(void);
  char vervangen(char string[255]);
  int sw=0, swM;

  while(sw==0)
  {
		printf("MENU:\n 1.Tekst intikken\n 2.Afsluiten\nNummer: ");
		scanf("%d",&swM);
		switch (swM)
		{
				 case 1 :  intikken();
							  break;
				 case 2 :  sw = 1;
							  break;
				 default :   clrscr();
								 printf("Foute Code!\n");
								 break;
		}
  }
  return 0;
}

int intikken(void)
{
  char zin[255], res[255], temp[255];
  char Kode[10], Vervang[10];
  char stop[]="stop";
  char c, *pos;


  FILE *fOpmaak;
  FILE *fInput = fopen("input.txt","w");

  printf("Tik zinnen in: \n");
  scanf("%[^\n]%c",&zin,&c);
  while(strcmp(zin,stop)!=0)
  {

		fOpmaak = fopen("opmaak.txt","r");
		while(!feof(fOpmaak))
		{

//here it goes wrong :(

			fscanf(fOpmaak,"%[^\n]%c",&Kode,&c);
			fflush(stdin);
			fscanf(fOpmaak,"%[^\n]%c",&Vervang,&c);


			do
			{
				pos = strstr(zin,Kode);
				if(pos != NULL)
				{
					 strncpy(res,zin,(strlen(zin)-strlen(temp)));
					 strcat(res,Vervang);
					 sprintf(temp,"%s",pos+strlen(Kode));
					 strcat(res,temp);
					 strcpy(res,zin);
				}

			}while (pos!= NULL );
			fclose(fOpmaak);
		 }
	fprintf(fInput,"%s\n",zin);
	scanf("%[^\n]%c",&zin,&c);
  }
  fclose(fInput);
  return 0;
}

Opmaak.txt could look like this:

[B ]
\33\50\163\63\102
[/B ]
\33\50\163\60\102
[I ]
\33
[/I ]
\33
[U ]
\33\46\144\61\104
[/U ]
\33\46\144\100

I'll first recommend some FAQ fixes.

• FAQ > How do I... (Level 1) > Get a line of text from the user/keyboard (C)
• FAQ > Explanations of... > Why fflush(stdin) is wrong
• FAQ > Explanations of... > Why it's bad to use feof() to control a loop

sprintf(temp,"%s",pos);
strncat(res,zin,(strlen(zin)-strlen(temp)));
strcat(res,Vervang);
sprintf(temp,"%s",pos+strlen(Kode));
strcat(res,temp);
strcpy(zin,res);

Adapted this a bit. I found that the filepointer doens't go further then the first record?

And concerning those faq-fixes, I know about them. But this is a school assignment and my school uses these, so I use them in my prog.

I'm sorry to hear that.

You may want to find better placement for this.

fclose(fOpmaak);

fclose(fOpmaak);

Thanks a million, that did the trick. Such a stupid mistake
(also had to insert a few other things, but now it works)

Well since you've completely failed to pay any attention whatsoever to my previous reply

you're on your own as far as I'm concerned.
