关于我最喜欢的城市的英语作文150字
我最喜欢的城市(my favourite city) Shanghai is my favorite city. I like it because I was born in there, and a lot of my family members and my friends live there. The shopping in Shanghai is cheaper than here, but it’s expensive in China. I have a lot of things to do there, like: shopping, playing, going to my friend’s home… And there’re also a lot of places that are interesting. In Shanghai, people speak the same language as I do. I was there for 13 years! I left there on August, 18th, 2005. And I was there because I was born in there and I lived there. There’re a lot of people in Shanghai. The people are like me. We all speak the same language. The people in Shanghai are busy and friendly. And Shanghai is also and international city. It’s beautiful and fancy. There’re a lot of tall buildings. That’s why Shanghai is my favorite city. It’s my home city. I love Shanghai!!! I’d like to go back to Shanghai, but just for a visit. Although Shanghai is good, I’d like to live here because I’d like to study here. I only get a little homework and the air here is flasher than Shanghai. The weather is hot in Shanghai. And the best time of year to go there is spring, because in spring, the weather is cool and warm. But some people asked me:” Why don’t we go there in the fall? The fall is also cool and warm.” I don’t think so, because in Shanghai, the fall is still very hot. I’d like to recommend this place to other because I want more and more people to know and visit my hometown. I hope if I ask my friends:” Have you ever been to Shanghai? Do you like Shanghai?” The answers shouldn’t be:” No, I haven’t been to Shanghai. And I don’t even know anything about Shanghai!” Now, I’ll recommend you to go to visit Shanghai in summer vacation or winter vacation or spring break or every time you’d like, you’d want, because Shanghai is a very nice city. If you go there, you’ll soon like it!

C语言编程 判断输入的一个数是否是5的倍数
C语言编程判断输入的一个数是否是5的倍数，编写方法如下图：
C语言的主要特点：
1. 简洁紧凑、灵活方便。C语言一共只有40个关键字，9种控制语句，程序书写形式自由，区分大小写。把高级语言的基本结构和语句与低级语言的实用性结合起来。C语言可以像汇编语言一样对位、字节和地址进行操作，而这三者是计算机最基本的工作单元。
2. 运算符丰富。C语言的运算符包含的范围很广泛，共有34种运算符。C语言把括号、赋值、强制类型转换等都作为运算符处理。从而使C语言的运算类型极其丰富，表达式类型多样化。灵活使用各种运算符可以实现在其它高级语言中难以实现的运算。
3. 数据类型丰富。C语言的数据类型有：整型、实型、字符型、数组类型、指针类型、结构体类型、共用体类型等。能用来实现各种复杂的数据结构的运算。并引入了指针概念，使程序效率更高。
4. 表达方式灵活实用。C语言提供多种运算符和表达式值的方法，对问题的表达可通过多种途径获得，其程序设计更主动、灵活。它语法限制不太严格，程序设计自由度大，如对整型量与字符型数据及逻辑型数据可以通用等。
5. 允许直接访问物理地址，对硬件进行操作。由于C语言允许直接访问物理地址，可以直接对硬件进行操作，因此它既具有高级语言的功能，又具有低级语言的许多功能。
6. 生成目标代码质量高，程序执行效率高。C语言描述问题比汇编语言迅速，工作量小、可读性好，易于调试、修改和移植，而代码质量与汇编语言相当。C语言一般只比汇编程序生成的目标代码效率低10%～20%。
7. 可移植性好。C语言在不同机器上的C编译程序，86%的代码是公共的，所以C语言的编译程序便于移植。在一个环境上用C语言编写的程序，不改动或稍加改动，就可移植到另一个完全不同的环境中运行。
8. 表达力强。C语言有丰富的数据结构和运算符。包含了各种数据结构，如整型、数组类型、指针类型和联合类型等，用来实现各种数据结构的运算。C语言的运算符有34种，范围很宽，灵活使用各种运算符可以实现难度极大的运算。
