#include <stdio.h>

int main(){

    struct point{
        int x;
        int y;
    };

    struct point p1 = {10, 20};
    struct point p2 = {40, 60};

    printf("Point1(%d, %d)\n", p1.x, p1.y);
    printf("Point2(%d, %d)\n", p2.x, p2.y);


    return 0;
}

// output:
// Point1(10, 20)
// Point2(40, 60)
