如何在C中创建Python类？

#include<stdio.h>

typedef struct {
    int x;
    int y;
} Point;

Point* create_point(int x, int y) {
    Point* point = (Point*)malloc(sizeof(Point));
    point->x = x;
    point->y = y;
    return point;
}

void print_point(Point* point) {
    printf("Point: (%d, %d)\n", point->x, point->y);
}

int main() {
    Point* point = create_point(3, 4);
    print_point(point);
    free(point);
    return 0;
}
