fseek() problems!

[hakeris1010]

Hello, i wrote a little program with fseek. It works good till it reaches the first fseek(). Then it crashes and stops responding. Its really weird.
My code:

ifstream inp("myfile.txt");

if(!inp.is_open()) return false;
inp.close();

FILE *f;
fopen("myfile.txt","rb");

fseek(f,0,SEEK_END); //there it crashes.

long s=ftell(f);
rewind(f);

fclose(f);

You don't initialize f. Combine lines 6 and 7 into
FILE *f = fopen("myfile.txt", "rb");
You don't need lines 1-4. Just check the return value from fopen instead:
if (f == NULL) return false;

Lastly, see if your operating system supposed stat(). If so then you can get the size of the file without even having to open it.

That works! Thanks!
