I get segmentation fault (core dumped) with the Try Catch... sad.png

void search() {
int logic;
cout << "Type the Year:\n";
cin >> logic;

for (int i = 0; i < storage.size(); i++) {
if (storage[i]->getYear() == logic) {
cout << storage[i]->getTitle() << endl;
/*
try {
cout
<< storage[i]->getPublisher() << endl
<< ((dmovies*)storage[i])->getDirector() << endl
<< ((cmusic*)storage[i])->getArtist() << endl
<< storage[i]->getDuration() << endl
<< storage[i]->getRating()
;
}
catch(int zero) {
zero = 5;
}
*/
cout << storage[i]->getYear() << endl;
}
}

Probably. I only know some JavaScript.

With which functions?

Test them individually, and if one doesn't work (like getYear) then you'd have to show us that code.

It's been a while since I did C++. As I recall & and * undo each other right? Like & is the address, and * is the pointer... so can you use * the way you're using it? If you're trying to access some random piece of memory that's what causes a core dump right?

But yeah, like I said, it's been a few years.

In general, write as little as possible before you stop and test things. It will feel slow at first, but it makes the process a lot easier.

Update: I got the error fixed on the delete function, I am using the vector for searching and adding also and I have a global int that tracks the size of the vector and I add that each time I add something, so I needed to add --storageTracker;  in the delete function ;

When I am searching for functions I try to match the year that you search with any year of the 3 child; video games, music and movies, then it mathes I want to print the entire thing. But the problem is I can't just do that, since I have certain getters on the child only like music has artist, so I dump the functions that aren't in parent in the try catch and well that causes errors.

Ah yeah, certain classes don't have access to each other, the parent child / public private stuff, it's been a while since I've messed with that.

yea & is for reference while * is for pointers
