c语言实现冒泡排序时出现数组溢出

Question

void po_sort(int* arr, int sz)
{
int i = 0;
for (i = 0; i < sz - 1; i++)
{
int flag = 1;
int j = 0;
for (j = 0; j < sz - 1 - i; j++);
{
if (arr[j] > arr[j + 1])
{
int tmp;
tmp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = tmp;
flag = 0;
}
}
if (flag == 1)
{
break;
}
}
}
int main()
{
int i;
int arr[10] = {10,9,8,7,6,5,4,3,2,1 };
int sz=sizeof(arr)/sizeof(arr[0]);
po_sort(arr,sz);

for (i = 0; i < sz; i++)
{
    printf("%d ", arr[i]);
}

越界就查看for循环访问，冒泡每次是相邻两个元素比较
