Bjarne Stroustrup
A C developer designs and writes programs using the C programming language. A C++ developer does the same but uses the C++ programming language. A C/C++ developer uses both C and C++.
C++ is a compiled language, not an interpreted language.
C++ is related to C, the language from which it is derived.
Yes, via Visual Developer Studio
Because it is used by almost every software developer. C++ is a strong, efficient and reliable programming language. You can use C++ to make everything from general applications, video games, and even operating systems.
C++ is generally a compiled language.
C, and its successor, C++, are arguably the best language in certain scenarios. C and C++ are very portable (runs well on different platforms simply by compiling to different targets), have a decent trade-off of speed and portability, and, arguably, has the largest following of developers that use C and C++ on a regular basis; usually the first language ported to any new Operating System is C or C++. However, C and C++ are just tools; there are times when assembler is the best language, and yet others when Java or ActionScript is the best language. Learning multiple languages makes a developer far more versatile in today's market, and one should aspire to learn multiple languages if they wish to pursue a career as a developer.
C++ doesn't use a framework; it is a general purpose, object oriented programming language derived from the C programming language. Specific implementations, such as Microsoft Visual C++, make use of frameworks.
While there are many companies and organisations implementing C++, language development is the sole responsibility of The C++ Standards Committee, or WG21 as they are officially known (ISO/IEC JTC1/SC22/WG21). Bjarne Stroustrup, the original developer of C++ and a founding member of the committee, currently sits as the Chair of the Evolution Working Group.
Yes, C++ is a high-level language.
Not part of the standard C-library, so you have to contact its developer.
Bjarne Stroustrup is the author of C++. However, no one "owns" this language.
