Points with a struct

A struct groups related values into one type. Here struct Point holds an x and a y. Complete two functions: make_point builds and returns a Point, and move_point shifts an existing one. With a pointer to a struct you reach its fields with ->, so p->x += dx moves it.

A struct Point with int x, y is given. Complete make_point(int x, int y) to build a Point, and move_point(struct Point *p, int dx, int dy) to shift it by (dx, dy) using ->.

/* Complete both functions. Do not write main(). */
struct Point {
    int x;
    int y;
};

struct Point make_point(int x, int y) {
    struct Point p;
    p.x = 0;   /* change this */
    p.y = 0;   /* change this */
    return p;
}

void move_point(struct Point *p, int dx, int dy) {
    /* change this — shift p by (dx, dy) using -> */
}
