Top Forums Programming Why is C/C++ considered low-level languages??? Post 302622259 by gabam on Wednesday 11th of April 2012 09:56:38 PM

Thanks for the explaining, it was really helpful. One more ambiquity that I have in my mind regarding the unix system calls like open, creat, write, read etc. The system calls that I have mentioned all all used for file manipulation. We also have functions like fopen, fclose in the same c language for the same purpose. Java, C++/C# also provide classes for file manipulation. Could you please tell me what is the difference between handling files using system calls in c language, and java/C++/C# classes and c functions like fopen etc. Isn't it that the system calls are one of the low-level properties of c language. And is it right to say that Java/C# depend on c language system calls to do their file manipulation jobs, that's why they are considered high-level languages. I will really appreciate your comments. Looking forward!
Thanks in advance!

DROP 
LANGUAGE(7) PostgreSQL 9.2.7 Documentation DROP LANGUAGE(7) NAME
DROP_LANGUAGE - remove a procedural language SYNOPSIS
DROP [ PROCEDURAL ] LANGUAGE [ IF EXISTS ] name [ CASCADE | RESTRICT ] DESCRIPTION
DROP LANGUAGE removes the definition of a previously registered procedural language. You must be a superuser or the owner of the language to use DROP LANGUAGE. Note As of PostgreSQL 9.1, most procedural languages have been made into "extensions", and should therefore be removed with DROP EXTENSION (DROP_EXTENSION(7)) not DROP LANGUAGE. PARAMETERS
IF EXISTS Do not throw an error if the language does not exist. A notice is issued in this case. name The name of an existing procedural language. For backward compatibility, the name can be enclosed by single quotes. CASCADE Automatically drop objects that depend on the language (such as functions in the language). RESTRICT Refuse to drop the language if any objects depend on it. This is the default. EXAMPLES
This command removes the procedural language plsample: DROP LANGUAGE plsample; COMPATIBILITY
There is no DROP LANGUAGE statement in the SQL standard. SEE ALSO
