Thread: K&R problem page

I've entered the program that is on page 29 of the K&R book. I use the Dev-cpp IDE on a Windows machine. The code compiles fine but I had to change a line in the code to get to program to work.

The code is below and i changed the text in bold from 0 to 1... which seems logical to me but why does the example in the book don't work? Has it something to do with the environment? Help appreciated...

Code:

#include <stdio.h>

#define MAXLINE 1000

int getline(char line[], int maxline);
void copy(char to[], char from[]);

int main(void)
{
  int len; /* current line length */
  int max; /* maximum length seen so far */
  char line[MAXLINE]; /* current input line */
  char longest[MAXLINE]; /* longest line saved here */
  
  max = 0;
  
  while ((len = getline(line, MAXLINE)) > 1) {
        if (len > max) {
                max = len;
                copy(longest, line);
        }
  }

  if (max > 0) /* there was a line */
  printf("%s", longest);
  
  return 0;
}

/* getline: read a line into s, return length */

int getline(char s[], int lim)
{
    int c,i;
    
    for (i=0; i < lim-1 && (c=getchar())!=EOF && c!='\n'; i++)
        s[i] = c;
        
    if (c = '\n') {
          s[i] = c;
          ++i;
    }
    
    s[i] = '\0';
    return i;
}

/* copy: copy 'from' into 'to'; assume its big enough */

void copy(char to[], char from[])
{
     int i;
     
     i = 0;
     while ((to[i] = from[i]) != '\0')
           ++i;
}

Ok, thanks guys...
1/ I retyped the code... (so I get a better feel for it) I'm new to c... and clearly made an error using the assignment operator...
2/ Didn't know about the EOF signaling
