About this site

In here we will discuss some program language,like the server script language PHP,shell,Python,Ruby and so on.In addition to this like the browser script language  javascript,and the compile language C,C++,Obj-C,Java and so on.Perhaps it has many errors,but I want you can find it and tell us.Thanks.

Below is some code segments which was wrote by the top main language in the internet.All the segment’s result is output a string “Hello World” in one line.
