Re: Help with code

Hi Daniel,

After you fix the problem mentioned by Alistair you will also need to 
allocate a buffer to read into. The character pointer sQuote you are  
passing to fgets is not initialised. You can either call malloc to 
allocate a buffer on the heap or for this exercise it would be easier 
use an on stack character array.

A 'segmentation fault' occurs when a process attempts to read or write 
from / to a region of memory that is not mapped into the process's 
address space.

       fgets(sQuote, 256, myfile);
       printf(sQuote);
       return 0;
}
--------------------------------------------------------------
I then compile the code with "gcc quote.cpp -o quote". quote.cpp is the name 
of the source file, and the file "quotes" is sitting in the same directory as 
the source. The compiler gives no errors but when I try to run it it says 
"Segmentation fault".
I have no idea what this means and this is the first time I have done any file 
I/O in linux. Does anyone know what this means and/or how to fix it?

Thanks,

Daniel
