It might be a good idea to implement structs to represent powerups. Within this struct, it would have an x and y value (this could be a struct in and of itself called point, which has two ints: x and y). The struct could also have a variable called type that represents what type of powerup it is, e.g., type = 1 for damage, and type = 2 for duplicating that ball. One easy way to represent all the possible powerups as integer values is through the use of enums (enumerations).

struct Powerup { Point position; int type; }

struct Point { int x, int y };

What is an enumerator? Microsoft definition: An enumeration type (or enum type) is a value type defined by a set of named constants of the underlying integral numeric type. this means that you can define named constants that have an underlying numeric value.

Example: enum Teachers { MATT = 1, JOE = 2 };

instead of literally typing 1, you could just write MATT, and it would represent the value 1, but the type is enum, not int.

Back to the context of powerups, you could make an enum as such:

enum POWERUPS { DUPLICATE = 1, MOARDAMAGE = 2, FASTER = 3 };

then make a struct:

struct Powerup { Point position; POWERUPS type; }

then create a struct with the desired powerup and position:

void main() { Powerup *ptrPowerup; create a pointer to a powerup ptrPowerup→position.x = screen_width / 2; set x and y values of the point struct within the powerup ptrPowerup→position.y = screen_height / 2; ptrPowerup→type = DUPLICATE; set the type variable within the powerup struct to DUPLICATE, which represent the underlying value of 1 } now everytime that you call ptrPowerup→type it will return DUPLICATE, which under the hood, represents 1.
