Question

Ok, so I’m not really sure what is going on here. I have a simple function, int foo(char *filename), that takes filename and counts the words in a file.

int foo(char *filename){

  FILE *inFile;
  int wordCount = 0;    

  printf("foo\n"); // test printf() statement (currently prints)

  char word[50];
  inFile = (&filename, "r");

  printf("infile\n");  // test printf() statement (currently prints)

  while (1){
    printf("while");   // test printf() statement (doesn't print)
    fscanf(inFile, "%s", word);
    if (feof(inFile))
        break;
    printf("%d", wordCount); //test printf() statement
    wordCount++;
  }
  fclose(inFile);
  return wordCount;

}

As you can see, I print “infile”, but not “while”. I get a segmentation fault. Does anyone have any idea why this doesn’t work Also, is my inFile = (&filename, "r"); statement correct? I’m not that great with pointers.

Answer 1

I’m surprised this line actually compiles:

inFile = (&filename, "r");

If you’re trying to open a file:

inFile = fopen(filename, "r");

EDIT:

And as mentioned, you need to end your printfs with \n or call fflush(stdout) or it will get buffered and not print.
