the C language, C language does not have to publish the source code, only need to post the compiled machine code (that is, you are common on Windows Xxx.exe file) published. It is impossible to eject C code from the machine code, so there is no such problem in any compiled language, and the language of interpretation must be published.This drawback is limited to the time you need to write software that needs to be sold to someone else for money. The good news is that the current Internet era, b
