Apple Certification Exam 9L0-509

C was essentially 9L0-509 the core language of C++ when Bjarne Stroustrup, decided to create a "better C". Many of the syntax conventions and rules still hold true and so we can even state that C was a subset of C++, most recent C++ compilers will also compile C code taking into consideration Testking 9L0-402 the small incompatibilities, since C99 and C++ 2003 are not compatible any more. You can also check more information about the C language on the C Programming Wikibook
C++ as defined by the ANSI standard in 98 (called C++98 at times) is very nearly, but not quite, a superset of the C language as it was defined by its first ANSI standard in 1989 (known as C89). There are a number of ways in which C++ is not a strict superset, in the sense that not all valid C89 programs are valid C++ programs, but the process 9L0-402 of converting C code to valid C++ code is fairly trivial (avoiding reserved words, getting around the stricter C++ type checking with casts, declaring every called function, and so on).

In 1999, C was revised and many new features were added to it. As of 2004, most of these new "C99" features are not there in C++. Some (including Stroustrup himself) have argued that the changes brought about in C99 have a philosophy distinct from what C++98 adds Pass4sure 9L0-509 to C89, and hence these C99 changes are directed towards increasing incompatibility between C and C++.
