Rewrite readlines to store lines in an array supplied by main, rather than calling alloc to maintain storage.How much faster is the program?

#include <string.h>

#define    MAXLEN    1000    /* maximum length of line */
#define    MAXSTOR   5000   /* size of available storage space */

int getline(char *, int);

/* readlines:read input lines */
int getlines(char *lineptr[], char *linestor, int maxlines){
    int len, nlines;
    char line[MAXLEN];
    char *p =linestor;
    char *linestop = linestor + MAXSTOR;

    nlines = 0;
    while((len = getline(line, MAXLEN)) > 0)
       if(nlines >= maxlines || p + len > linestop)
           return -1;
       else{
            line[len - 1] = '\0';    /* delete newline */
            strcpy(p ,line);
            lineptr[nlines++] = p;
            p += len;
       }
    return nlines;
}
