Structure data types are useful way to package related data and have them behave like a single variable.
Declaring a simple struct
that holds two int
members:
struct point
{
int x;
int y;
};
x
and y
are called the members (or fields) of point
struct.
Defining and using structs:
struct point p; // declare p as a point struct
p.x = 5; // assign p member variables
p.y = 3;
Structs can be initialized at definition. The above is equivalent to:
struct point p = {5, 3};
Structs may also be initialized using designated initializers.
Accessing fields is also done using the .
operator
printf("point is (x = %d, y = %d)", p.x, p.y);
