why do i get this problem ?

http://uppix.net/e/5/0/262bab6e34bce...9e4676d724.jpg

Code:

---

Starting D:\noob\addressbook\debug\addressbook.exe...
D:\noob\addressbook\debug\addressbook.exe exited with code -1073741674

---

The error code means that there was a priviliged instruction where it shouldn't be allowed.

I guess that you tried to access some uninitialised memory.
