Structures

1. to avoid creating different variables for each entity and their respective variables for each and every attribute, we can use structures.
2. Structure is a group of variables of different data types represented by a single name.
3. Structures are the basic foundation for objects and classes in C
4. Serialization of data
5. Passing multiple arguments in and out of functions through a single argument
6. Data structures such as linked lists, binary trees, and more

struct point {
    int x;
    int y;
}

• ’ . ’ is the member accessing operator

/* draws a point at 10, 5 */
int x = 10;
int y = 5;
draw(x, y);

• Using structs, we can pass a point argument:

/* draws a point at 10, 5 */
struct point p;
p.x = 10;
p.y = 5;
draw(p);
