Thread: a few questions on array of ptrs

Trying hard to find why even after allocating data my program gives o/p as:

#
Hi
Hi
Hi
Hi
and then infinite loop...

Code:

FILE *f;
	  int i=0;
	  int j=0;
	  char ch;
	  char *data[6];
	  for(i=0;i<6;i++){
	   if ((data[i] = (char *) malloc(sizeof(char) * 600)) == NULL)
	      printf("Error: Null pointer returned\n");
	  }
	  clrscr();
	  if((f=fopen("test.mul","r"))==NULL)
	  {
	  printf("Error\n");
	  }
	  ch = fgetc(f);
	  printf("%c\n",ch);
	   while (!(feof(f))){
		for (i=0;i<6;i++){
		     printf("Hi\n");
			 do{
			   ch=fgetc(f) ;
			   (data[i])[j++] = ch;
			 } while(ch!='#');

			 (data[i])[j]='\0';
		   }
		   printf("%s",data[0]);
	       }
	  fclose(f);
	  for(i=0;i<6;i++)
	  free(data[i]);

but a good point is that when i use a simple while !EOF with fgetc, the entire file is being printed as it is.
