答案：Cloud computing offers several advantages, including:
- Cost savings: Companies can reduce their infrastructure costs by using cloud services instead of maintaining their own hardware.
- Scalability: Cloud services can easily scale up or down based on demand, allowing businesses to only pay for what they need.
- Flexibility: Users can access cloud services from anywhere with an internet connection, enabling remote work and collaboration.
- Disaster recovery: Cloud providers often have backup systems in place, ensuring data can be recovered in case of a disaster.
- Automatic updates: Cloud services are typically updated regularly by the provider, ensuring users have access to the latest features and security patches.
2. Explain the difference between HTTP and HTTPS.
答案：HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting data over the internet. It is not secure, meaning that the data being transmitted can be intercepted and read by anyone. HTTPS (Hypertext Transfer Protocol Secure), on the other hand, is a secure version of HTTP. It uses encryption to ensure that data is encrypted before transmission, making it much more difficult for hackers to intercept and read. HTTPS is commonly used for secure online transactions, such as submitting credit card information or personal details.
四、编程题
请编写一个Python程序，实现计算圆的面积和周长的功能。

程序应该满足以下要求：
- 提示用户输入半径值。

- 将半径值转换为浮点数。

- 使用给定的半径值计算圆的面积和周长。

- 打印输出计算结果，保留两位小数。

答案：
radius = float(input("请输入半径值："))
pi = 3.14159
area = pi * radius * radius
circumference = 2 * pi * radius
print("圆的面积为：{:.2f}".format(area))
print("圆的周长为：{:.2f}".format(circumference))
