Thread: Overwriting Array with New Array

I'm working with a program at the moment that needs to have an array of undefined length (and of type 'record', which is a struct) that is initialized in a separate function, sorta like so:

Code:

class MyClass {
...
private:
    record knowledgeBase[];
}
...

void MyClass::initKnowledgeBase() {
    knowledgeBase[] = {
        ...etc...
    }
}

I've been looking everywhere and tried everything I could think of. Is there any way to make it so that every time initKnowledgeBase() is called, I can recreate the variable-length knowledgeBase[] array?
