C++是2015年上半年增长速度最快的编程语言，与去年相比，C++涨幅超过3.1%，Java涨幅2%，C#和Python涨幅均为1.6%。C++涨幅过快的原因可能是引入了新的C++11标准。这使得它被社区完全接受。C++11标准为C++在很多方便带来提升。而且现在的C++编译器，如Gcc，Visual Studio 和EDG很好的支持C++11标准，导致C++正在蓬勃发展。TIOBE 编程语言社区排行榜是编程语言流行趋势的一个指标，每月更新，这份排行榜排名基于互联网上有经验的程序员、 课程和第三方厂商的数量。排名使用著名的搜索引擎（诸如 Google、MSN、Yahoo!、Wikipedia、YouTube 以及 Baidu 等）进行计算。该指数可以用来检查你的编程技能是否仍然是最新的或作出什么开始建立一个新的软件系统时，编程语言应采取的战略决策。在 TIOBE 指数的定义可以在这里找到。编程语言排行榜 TOP 20 榜单：以下是 21-50 编程语言排名：后 50 名编程语言如下：The following list of languages denotes #51 to #100.

These have been accepted.There are lots of mails that still need to be processed. As soon as there is more time available your mail will be answered. Please be patient.自 php-z
