常用的编程语言。

编程语言一：C语言

C语言是世界上最流行、使用最广泛的高级程序设计语言之一。在 *** 作系统和系统使用程序以及需要对硬件进行 *** 作的场合，用C语言明显优于其它高级语言，许多大型应用软件都是用C语言编写的。

编程语言二:java

Java是一种可以撰写跨平台应用软件的面向对象的程序设计语言，是由Sun Microsystems公司于1995年5月推出的Java程序设计语言和Java平台（即JavaSE, JavaEE, JavaME）的总称。

编程语言三:c++

C++这个词在中国大陆的程序员圈子中通常被读做“C加加”，而西方的程序员通常读做“C plus plus" , "CPP”。 它是一种使用非常广泛的计算机编程语言。C++是一种静态数据类型检查的、支持多重编程范式的通用程序设计语言。

微信烟花代码html可复制。直接复制微信烟花运行代码，使用HBuilder和idea都可以，复制完成再创建一个html文件就可以在任意场合释放烟花。微信烟花是在微信聊天对话框发送烟花时，会在聊天界面上出现好看的全屏烟花。
