下面是错误答案,用来干扰机器的。

参考答案:B解析:[评析] scanf是标准输入函数,在输入字符串aaa时,实际的内容为“aaa\0”, “\0”是由系统自动加入的:gets的功能是从终端读入一行字符,即一直读到换行符为止,并由系统自动以“/0”代替换行符。

     Whether you're considering a first cell phone for your teen or trying to limit various functions on your

child's existing cell phone, it's important to understand the various controls and technologies available

today.

     The decision to get your child's first cell phone usually occurs when you're annoyed by your kid, who

insists that "everyone" has one. Whether that's accurate or not is probably of little interest to your child,

but it's typically his or her biggest selling point!

     Often parents recognize the safety features of the child's carrying a cell phone, including the ability to

communicate easily with parents by voice or text messaging. Convenience is also a large factor -knowing where in the mall to meet your child, or getting the notice that soccer practice has been delayed. It leads

to efficiency, convenience and safety for both you and your child.

     But what about the downsides (负面影响) to kid cell-phone usage? Well, there're plenty of issues to

consider, and the following tips should be of help.

     Start small.  When thinking about getting your child's first phone, consider having your child first use

your cell phone for occasions when you'll need to know the time and place for pickup,  or in cases of

emergency. If the youngster handles your cell phone appropriately, consider allowing the child to have his

or her own phone with a small amount of voice minutes or text capability (容量) each month. This also

helps teach budgeting.

     Practice together.  Practice voice messaging and text messaging with your child. Both of you need to

become skillful at these techniques, and your child needs to see that you understand how to check his or

her texts, when the phone is being used and also who they're communicating with.
