What is a node struct? A node struct is used to represent an element, in our case, a brick, within a list.

An example of a structure for a node is as follows:

struct BrickNode
{
    bool Active;
    int X, Y;          // Position on screen
    int Width, Height; // Size of hitbox for brick
    BrickNode* next;   // Pointer to the next brick node
};

Format for linking nodes together:

newBrick->next = BrickList;

This line of code is linking the new brick node into the list. here's how it works: newBrick, which is a node for each brick, is set to the point to the current head of the list essentially putting a new node at the beginning of the list. This is done with the →next.
