今日无意浏览一网站的时候发现了一条新闻，11月编程语言排行榜中C与JAVA的差距变小了，这个差距指的不是功能及性能方面的，而是使用率上，05年的时候JAVA与C曾经接近过一次，11月份这样的现象又重现了。

下面是TIOBE Programming Community Index for November 2009的一些数据及图片。这些均来自于TIOBE官网。

从上图中我们可以看出JAVA与C非常接近了。

 而从上面这幅图中我们可以看到JAVA略有下降，C有回升的趋势。

C语言不知道有多少朋友学过？我的感觉是语法简单精练，很适合刚接触编程的朋友，另外C作为有30多年历史的语言，其优秀的特性至今仍被很多朋友使用。而JAVA由于其跨平台及面向对象等特性普及率越来越高，成为越来越多朋友的首选编程语言。

下面是TIOBE官网的一些原文。

November Headline: C is closing its gap with Java

The difference between the number 1 and 2 of the TIOBE index is getting smaller. C is only a little over 1% behind Java now. Last time C and Java were so close was in 2005. Both languages show a long-term downtrend, but Java's downtrend appears to be steeper. In two months' time TIOBE will announce the programming language of the year 2009. Candidates so far are: C, C#, PHP and may be even Objective-C.

The TIOBE Programming Community index gives an indication of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, MSN, Yahoo!, Wikipedia and YouTube are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.

不知道各位朋友对C及JAVA有何看法呢？
