How can I use structs in functions in C++?

You can pass structs to functions by value or by reference. Would you like to see an example?

Yes, please provide an example of passing a struct by reference.

Sure! Here's a simple example:

struct Point {
    int x;
    int y;
};

void movePoint(Point &p, int dx, int dy) {
    p.x += dx;
    p.y += dy;
}

int main() {
    Point p = {1, 2};
    movePoint(p, 3, 4);
    // p is now at (4, 6)
}

This modifies the original struct.

What about returning a struct from a function?

You can return a struct by value. Here's an example:

Point createPoint(int x, int y) {
    Point p;
    p.x = x;
    p.y = y;
    return p;
}

This creates a new Point struct and returns it.
