C语言实现简单的冒泡排序

#include<stdio.h>
void BubbleSort(int *arr, int as)
{
    int i = 0;
    int j = 0;
    //for (j = as; (j-1) > 0; j--)
    for (j = (as-1); j > 0; j--)
    {
        for (i = 0; i < j; i++)
        {
            if (*(arr + i) > *(arr + i + 1))
            {
                int tmp = 0;
                tmp = *(arr + i);
                *(arr + i) = *(arr + i + 1);
                *(arr + i + 1) = tmp;
            }
        }
    }
}
int main()
{
    int i = 0;
    int arr[] = { 1, 3, 5, 4, 2, 8, 7, 9 };
    int sz = 0;
    sz = sizeof(arr) / sizeof(arr[0]);
    BubbleSort(arr, sz);
    for (i = 0; i < sz; i++)
    {
        printf("%d\n", arr[i]);
    }
    return 0;
}
