This program (copied from "The C programming language" by Kernigham/ 
Ritchie)
doesn't work fine.
The operator enters some strings of characters and at EOF the program has to
display the longest string typed.........and this doesn't happen.
Where is the problem ?Thanks a lot.


#include <stdio.h>
#define  MAXLINE 100
int max;
char line[MAXLINE];
char longest[MAXLINE];
int getline(void);
void copy(void);
main()
{

   int  len;
  extern int  max;
   extern char longest[MAXLINE];
   max=0;

   while ((len=getline()) > 0)
      if  (len > max)
      {
       max = len;
        copy();

      }
   if (max > 0)
    printf("%s",longest,'\n');

   return 0;

}

int  getline(void)
{

   int c,i;
   extern char line[];
   for (i=0;i<MAXLINE-1 && (c=getchar()) !=EOF && c !='\n';++i)

       line[i] = c;
   if (c=='\n')
   {
     line[i] = c;
       ++i;
   }
      line[i]='\0';

      return i;
}

void copy(void)
{
   int i;
   extern char line[];
   extern char longest[];
   i=0;
     while ((longest[i] = line[i]) !='\0')
             ++i;



}
