How can I use structs in functions in programming?

You can pass structs to functions as parameters, return them from functions, or even use them as function return types.

Can you give me an example of a struct being used in a function?

Sure! Here's a simple example in C:

struct Point {
    int x;
    int y;
};

void printPoint(struct Point p) {
    printf("Point(%d, %d)\n", p.x, p.y);
}

You can call printPoint(myPoint); to print the coordinates.

What if I want to modify the struct inside the function?

You can pass the struct by reference using pointers. This way, any changes made inside the function will affect the original struct.

Can you show me how to do that?

Absolutely! Here's an example:

void movePoint(struct Point *p, int dx, int dy) {
    p->x += dx;
    p->y += dy;
}

You would call it like this: movePoint(&myPoint, 5, 3); to move the point.
