奇数前，偶数后排序

void move(int *arr,int sz)
{
int left = 0;
int right = sz - 1;
while (left < right)//left必须小于right 防止指针越界
{
//从左边找偶数
while (left < right && arr[left] % 2 == 1)
{
left++;
}
//从右边找奇数
while (left < right && arr[right] % 2 == 0)
{
right--;
}
//交换
if (left < right)
{
int tmp = arr[left];
arr[left] = arr[right];
arr[right] = tmp;
}
}
}
void print(int* arr, int sz)
{
int i = 0;
for (i = 0; i < sz; i++)
{
printf("%d ", *(arr + i));
}
}
int main()
{
int arr[] = {1,2,3,4,5,6,7,8,9,10,11,23,44};

int sz = sizeof(arr)/sizeof(arr[0]);
move(arr,sz);
print(arr,sz);

return 0;
}
