Claiming to know C++ is like claiming you can bend the Matrix. Sure, Neo thought he was special until Morpheus challenged him to prove it. Then reality hits harder than a segmentation fault, and suddenly your program's memory is sprawled out on the dojo floor like a defeated rookie.
The segmentation fault (core dumped) error is basically C++'s way of saying "You're not The One, you're just another programmer who forgot to check their pointers." Your confidence in memory management just got kung-fu kicked into oblivion.
