    Reading and printing a text file

    I'm finishing up a schoolproject in C.

    I was doing a helpfunction, wich should print information onto the console, the information is in a .txt file

    Code:
    #include <conio2.h>
    #include <stdio.h>
    #include <stdlib.h>
    
    void help(void) {
        char line[80];
        FILE *help;
    
        help = fopen ("help.txt", "r");
        if (help == NULL)
        {
            printf("help.txt kan niet geopend worden!");
        }
        do {
            fscanf(help,"%[^/n]",line);
            printf("%s/n",line;
        } while (!feof(help));
    
        fclose(help);
    
        getch();
    }
    the function seems to be in a non-stop loop, printing only the first part of the txt-file
    if I put only a few words into it, it works fine, but when I put a whole text in the file, it goes crazy

    If help is NULL, return.
    Avoid using feof() as a loop condition: http://faq.cprogramming.com/cgi-bin/...&id=1043284351
    Use fgets instead of fscanf.
