Thread: Noob help

Hey hi all! i am reading The C Programming Lenguage, doing the exercies and i need some help

Exercise 1-17. Write a program to print all input lines that are longer than 80 characters.

Code:

#include <stdio.h>

#define MIN 2              /* print lines longer than this one */
#define MAXLENGHT  10000     /* the main arrays where all the lines will we saved */
#define MAXLINE  1000      /* mac line length */

int getline(char s[], int lim);
void copy_to_lines(char from[], char to[], int position, int len);
int strlen(char s[]);

int main()
{
    char line[MAXLINE];
    char lines_saved[MAXLENGHT];
    int current_position = 0;
    int len;

    while(( len = getline(line, MAXLINE)) > 0)
    {
        if (len > MIN) {
            copy_to_lines(line, lines_saved, current_position, len);
            current_position += len;
        } 
    }
    printf("%s", lines_saved);

    return 0;
}

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

    for (i = 0; i < lim && (c = getchar()) != EOF && c != '\n'; ++i)
    {
        s[i] = c;
    }
    if (c == '\n') {
        s[i] = c;
        ++i;
    } 

    return i;
}

void copy_to_lines(char from[], char to[], int position, int len)
{
    int i;

    for(i = 0; i < len; ++i)
    {
        to[position] = from[i];
        ++i;
        ++position;
    }
}

I am not using any resource not present in the book at that point.
Any help is much appreciated.
Thanks.
