As the C++ programming language evolved, the standard library evolved with it. The first addition to the C++ language standard library was the stream I/O library which provided facilities to replace the traditional C functions such as printf or scanf. Later, among the very most significant additions to the standard library, were large amounts of the Standard Template Library.

C++ language is sometimes called a hybrid language.

It is possible to write object oriented and procedural code in the same program in C++language. This has caused some concern that some C++ programmers language are still writing procedural code, but are under the impression that it is object oriented, simply because they are using C++ language. Often it is an amalgamation of the two. This usually causes very most problems when the code is revisited or the task is taken over by another coder.  C++ language continues to be used and is one of the preferred C programming languages to develop professional applications.
