Thread: Trying to print a data file with words and numbers

Hi, I'm trying to create a menu for a program by printing a data file. This is what it looks like

WELCOME TO MAZE-RUNNER DEMO


THIS IS NOT YOUR MAZE RUNNER! This is a demo of possible Maze Runner Levels.

The Levels are:

Level 0: Drive the Mouse.
You may use the a,s,d,w commands in the predefined
visible maze.

Level 1: Mouse Discovers
You may use Level 0 commands and r,l and m commnad
in the predefined hidden maze

Level 2: Mouse Explores
You may use Level 1 commands and the n command

Level 3: Da Frills
Not provided.


and i'm trying to print it like this

insert

Code:

#include<stdio.h>
#include "menu.h"

main()
{
       int lvl = 100;
        char f;
        FILE *fp;
        char words [100];



       fp = fopen ("demo_intro", "r");

        fscanf(fp, "%s", &f);
        fprintf(fp, "%-100.100s",f);
}

I have never used fprint,fscan, or fopen before so I don't know how to use them at all. I am hoping someone will first be able to tell me if i can actually print that data file and secondly, teach me how to open and print it using code. Thank you a lot.

I did look it up, that's how i got that code, but i don't understand why it won't work because it gives me segmentation fault.

First, you don't check that you successfully opened the file. Second,

Code:

char f;
...
fscanf(fp, "%s", &f);

you're attempting to use the character string formatter, %s, to read a single character.

Something like this:

Code:

fgets(buffer, BUF_SIZE, fh);
printf("buffer: %s\n", buffer);

Do you not have documentation for your compiler and it's libraries?
