Help for C code

I just want to make a program get current cursor position then store it in array then play reverse of event with a loop and SetCursPos function i tried some codes but still could not do it here is code:

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>


int main()
{
    POINT p;
    int arr[2];
    GetCursorPos(&p);
    arr[0] = p.x;
    arr[1] = p.y;

    int numPositions = sizeof(arr) / sizeof(p);
    for (int i = numPositions - 1; i >= 0; i--) {
        SetCursorPos(arr.[i].x, arr[i].y);
        Sleep(100);
}
}

and i tried another one too :

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>

int main()
{
    POINT p;
    int arr[2] = {0};
    GetCursorPos(&p);
    arr[0] = p.x;
    arr[1] = p.y;
    int numPositions = sizeof(arr) / sizeof(int);
    for (size_t i = numPositions; i > 0; i--)
    {
        if (arr[i-1].x >= 0 && arr[i-1].x && (arr[i-1].y >= 0 && arr[i-1].y))
    {
    SetCursorPos(arr[i-1].x, arr[i-1].y);
    Sleep(100);
    }
    }
}

im confused how to do what i planned in my mind maybe there is better ways for create what i want pls help!
