Name mangling style in c++

Question

Hi
I have heard that main function name mangling is always of c style even if we write code in C++.
Addition to main function , static variable are also having name mangling as per c style in case of c++ code.. where as extern and global variables will follow c++ name mangling style for c++ code..
Above is always true or it is compiler specific ?

Thank you Akib Reza ... Any thought on external , static and global variable in terms of name mangling ? I presume that along with function names, these are some variables which gets name mangling.

Yes, they do. I use the MSVC compiler. I think this thread will give you an idea.

I don't know much about name mangling.
