Question

I cant figure out how to properly pass this double pointer…. nothing i’ve tried works…

class myClass{

    MyClass *attribClass;
}

void derp(MyClass **myA) {
    // recursively calls down classes....
    derp(&(myA->attribClass)); // what am i doing wrong?
}

int main() {

    MyClass *myClass = new MyClass;

    myClass.attribClass = *whatever code to initialize a long linked list of MyClass's*;

    derp(&myClass); 
}

Answer 1

There’s several issues:

class MyClass {  //  Change to "MyClass".

public:   //  Need to make it public or it can't be accessed by "derp()"
          //  Did you intend "derp()" to be a class member?

    MyClass *attribClass;
}; //  missing semicolon

void derp(MyClass **myA) {
    // recursively calls down classes....
    derp(&((*myA)->attribClass)); // what am i doing wrong?
}

And in the last one, you need to deference myA once before you access attribClass.

derp(&((*myA)->attribClass)); // what am i doing wrong?
