Need help please to pass struct array to fucntion

Code:

---

#include <stdio.h>
        typedef struct
        {
                int x;
                int y;
        }POINT;


        void display(POINT);


        int main()
        {
                int i;
                POINT p1[10];
                for (i = 0; i < 10;i++)
                {
                        p1[i].x =i*2;      //
                        p1[i].y = i * 4;  //
                }
                display(p1);
               
        }
        void display(POINT p[])
        {
                for (int i = 0; i < 10;i++)
                printf("The coordinates of the point are: %d %d \n", p[i].x, p[i].y);
        }

---

display(p1); seems not working to pass to function display I tried p1[] not working any advise please thank you.

> void display(POINT);
> void display(POINT p[])

Did you ignore errors and warnings when compiling? Because your declaration doesn't match the definition.

        }
        display(p1);


}

Yes my mistake, This format is working perfectly, How can I declare it in like first style writing? thank you

If you mean have the declaration above main and the declaration below, just copy the function header, paste it above main, and add a semi-colon.

Code:

---

#include <stdio.h>

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

void display(POINT p[]);

int main()
{
    int i;
    POINT p1[10];

    for (i = 0; i < 10; i++)
    {
        p1[i].x = i * 2;
        p1[i].y = i * 4;
    }

    display(p1);
}

void display(POINT p[])
{
    for (int i = 0; i < 10; i++)
        printf("The coordinates of the point are: %d %d \n", p[i].x, p[i].y);
}

You should used named constants instead of the magic number 10.

You should also pass the number of elements to your function along with the array, instead of hard-coding this value inside of the function.
