【IT168 资讯】Tiobe今日发布了12月份的编程语言排行榜。榜单中，公司开发的编程语言表现优异，微软的C#、苹果的Objective-C和Adobe的ActionScript评级均创各自的历史新高。
在11月榜单中，此次 C与Java的差距越来越小，仅相差1%；Objective-C更是生猛，从上月的第18位飙升到了第13位。有前进的当然也少不了相对后退的，还处于第17位的D语言已经跌至第20位。
本月中，微软的C#达到了它的最高评级，已经达到6.258%，涨幅达+1.20%，涨势明显，并很有可能成为Tiobe2009年度编程语言的评选中取胜。另外一个是苹果公司的Objective-c，同样打破了自己的记录，距离与排名前十越来越近，并获得了“A“的评级。同时，Adobe公司的ActionScript也获得了高分，重新进入了Top20。
