C/code/点类定义和使用.cpp

#include <stdio.h>

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

void setxy(Point *point, int new_x, int new_y) {
    point->x = new_x;
    point->y = new_y;
}

void displayxy(Point point) {
    printf("(%d,%d)", point.x, point.y);
}

int main() {
    Point point1 = {3, 4};
    Point point2 = {5, 6};

    printf("The first point is:");
    displayxy(point1);
    printf("\n");

    printf("The second point is:");
    displayxy(point2);
    printf("\n");

    return 0;
}
