static pointer to an array of class instances

Question

I have a class Product:

class Product{
public:
    int weight;
    static *Product listOfProducts;
}

int main(){
    Product ProductList[100];
    *Product listPointer;
    listPointer = ProductList;
    
    Product::listOfProducts = listPointer;
}

I want to get a static pointer field to an array of this class' instances, but I have a bad understanding of how to do this.

I guess you want an array of instances of the class (not an array of the class members) — 463035818_is_not_an_ai

Your syntax is wrong. Namely, you have placed * in the wrong places, you are missing a semicolon after the Product class declaration, and you are missing a definition for the Product::listOfProducts variable.

Try this instead:

class Product{
public:
    int weight;
    static Product* listOfProducts;
};

Product* Product::listOfProducts;

int main(){
    Product ProductList[100];
    Product* listPointer;
    listPointer = ProductList;
    
    Product::listOfProducts = listPointer;

    // or simply:
    // Product::listOfProducts = ProductList;
}
