In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for the ...
The following outline is provided as an overview of and topical guide to C++: C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. [1]
extrn a, b, c; putchar(a); putchar(b); putchar(c); putchar('!*n'); } a 'hell'; b 'o, w'; c 'orld'; The program above prints hello, world! on the terminal, including a newline character. The phrase is divided into multiple variables because in B a character constant is limited to four ASCII characters.
Class (computer programming) In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state ( member variables) and implementations of behavior (member functions or methods ). [1] [2] [a]

For example, in C++ : x = 5; x = x + 1; // {x > 1} The braces included in the comment help distinguish this use of a comment from other uses. Libraries may provide assertion features as well. For example, in C using glibc with C99 support: #include <assert.h> int f(void) { int x = 5; x = x + 1; assert(x > 1); }
Profiling is achieved by instrumenting either the program source code or its binary executable form using a tool called a profiler (or code profiler). Profilers may use a number of different techniques, such as event-based, statistical, instrumented, and simulation methods.

Statement (computer science) In computer programming, a statement is a syntactic unit of an imperative programming language that expresses some action to be carried out. [1] A program written in such a language is formed by a sequence of one or more statements. A statement may have internal components (e.g. expressions ).
struct X a = (struct X){4, 6}; // The equivalent in C++ would be X{4, 6}. The C syntactic form used in C99 is supported as an extension in the GCC and Clang C++ compilers. foo(&(struct X){4, 6}); // The object is allocated in the stack and its address can be passed to a function.
