Operators in C and C Plus Plus

- The title of this article is incorrect because of technical limitations. The correct title is Operators in C and C++.
This is a list of operators in C++ programming language. Third column tells whether or not the operator in question also exists in C99 (and also in C89, since the two versions of the C language contain the same set of operators).
The following operators are sequence points in all three languages: &&, ||, ?:, and ,
C++ also contains the type conversion operators const_cast, static_cast, dynamic_cast, and reinterpret_cast which are not listed in the table for brevity.

Notes
Some of the functions listed above are sometimes given longer form "names". For example, += and -= are often called PlusEqual and MinusEqual. This is also useful in performing internet searches, as major sites like google do not allow a search for "+=" for example.
