//Instead of a list of variables like:
//
//int lengthofrectangle1 = 10;
//int heightofrectangle1 = 2;
//int positionxofrectangle1 = 0;
//int positionyofrectangle1 = 0;
//int lengthofrectangle2 = 4;
//int heightofrectangle2 = 3;
//int positionxofrectangle2 = 0;
//int positionyofrectangle2 = 0;
//
//we can group them together by creating a rectangle "object".

struct rectangle {
  int height;
  int length;
  int positionx;
  int positiony;
  int number;};

//We can then initialize them with

//  struct rectangle rectangle1;
//  struct rectangle rectangle2;
//  rectangle1.height = 10;
//  rectangle1.length = 2;
//  rectangle1.positionx = 0;
//  rectangle1.positiony = 0;
//  rectangle1.number = 1;
//  rectangle2.height = 4;
//  rectangle2.length = 3;
//  rectangle2.positionx = 0;
//  rectangle2.positiony = 0;
//  rectangle2.number = 2;
//
//  print_rectangle_properties(rectangle1);
//  print_rectangle_properties(rectangle2);}

//then pass the entire rectangle to a procedure:

void print_rectangle_properties ( struct rectangle rec) {
  printf("height of rectangle%d is %d\n", rec.number, rec.height);
  printf("length of rectangle%d is %d\n", rec.number, rec.length);
  printf("xposition of rectangle%d is %d\n", rec.number, rec.positionx);
  printf("yposition of rectangle%d is %d\n", rec.number, rec.positiony);}


//Now whenever we need to print a rectangle, we can just use
//print_rectangle_properties(rectangle1);
//this continues to work for new rectangles we define later in the program.



//we can similarly create circles for our cad system.

// circle stuff
struct circle {
  int radius;
  int positionx;
  int positiony;
  int number;};
