while True:

while 1 > 0:

while 0 > 1:

while 5 == 5:

while False:

while 0:

while 1:

while None:

i = i + 1

i += 2

i = i - 2

i -= 2

```python i = 0 while i < 5: print("Hi") i += 1 ```

```python i = 1 while i <= 5: print("Hi") i += 1 ```

```python i = 5 while i > 0: print("Hi") i -= 1 ```

以上皆是

```python i = 5 while i > 0: print(i) i -= 1 ```

```python i = 1 while i <= 5: print(i) i += 1 ```

```python i = 5 while i >= 1: print(i) i -= 1 ```

以上 A 和 C 都正確
