Revise the main routine of the longest-line program so it will correctly print the length of arbitrarily long input lines,and as much as possible of the text.

#include<stdio.h>
#define MAXLINE 1000

int getlines(char line[], int minline);
void copy(char to[], char from[]);

/*print the length of the input line and the lines content*/
main()
{
        int len;
        int max;
        char line[MAXLINE];
        char longest[MAXLINE];

        while((len = getlines(line, MAXLINE)) > 0)
        printf("%d %s",len, line);
            if(len > max){
                max = len;
                copy(longest,line);
            }
        if(max > 0)
                printf("%s",longest);
        return 0;

}

int getlines(char s[],int lim)
{
int c,i;

        for(i=0; i<lim-2 && (c = getchar())!= EOF && c!='\n';++i)
                s[i] = c;
        if( c == '\n')
        {
            s[i] = c;
            ++ i;
        }
        s[i] = '\0';
        return i;
}
void copy(char to[],char from[])
{
        int i;

        i = 0;
        while((to[i] = from [i]) != '\0')
                ++ i;

}
