C++ Language Reference


For the latest documentation on Visual Studio 2017, see Visual Studio 2017 Documentation.

For the latest documentation on Visual Studio 2017, see C++ Language Reference on docs.microsoft.com. This reference explains the C++ programming language as implemented in Microsoft Visual C++. The organization is based on The Annotated C++ Reference Manual by Margaret Ellis and Bjarne Stroustrup and on the ANSI/ISO C++ International Standard (ISO/IEC FDIS 14882). Microsoft-specific implementations of C++ language features are included.

See the following tables to quickly find a keyword or operator:

Lexical Conventions
Fundamental lexical elements of a C++ program: tokens, comments, operators, keywords, punctuators, literals. Also, file translation, operator precedence/associativity.

Basic Concepts
Scope, linkage, program startup and termination, storage classes, and types.

Standard Conversions
Type conversions between built-in, or "fundamental," types. Also, arithmetic conversions and conversions among pointer, reference, and pointer-to-member types.

Operators, Precedence and Associativity
The operators in C++.

Types of expressions, semantics of expressions, reference topics on operators, casting and casting operators, run-time type information.

Lambda Expressions
A programming technique that implicitly defines a function object class and constructs a function object of that class type.

Expression, null, compound, selection, iteration, jump, and declaration statements.

Storage-class specifiers, function definitions, initializations, enumerations, class, struct, and union declarations, and typedef declarations. Also, inline functions, const keyword, namespaces.

The portion of a declaration statement that names an object, type, or function. Abstract declarators, type names, initializers, function declarations and definitions, arrays, references.

Classes, Structures, and Unions
Introduction to classes, structures, and unions. Also, member functions, data members, bit fields, this pointer, nested classes.

Derived Classes
Single and multiple inheritance, virtual functions, multiple base classes, abstract classes, scope rules. Also, the __super and __interface keywords.

Member-Access Control
Controlling access to class members: public, private, and protected keywords. Friend functions and classes.

Special Member Functions
Special functions unique to class types: constructors, destructors, conversion functions, assignment operator, operator new and operator delete functions.

Overloaded functions, declaration matching, argument matching. Also, overloaded operators, rules for operator overloading.

Exception Handling
C++ exception handling, structured exception handling (SEH), keywords used in writing exception handling statements.

Assertion and User-Supplied Messages
#error directive, the static_assert keyword, the assert macro.

Template specifications, function templates, class templates, typename keyword, templates vs. macros, templates and smart pointers.

Event Handling
Declaring events and event handlers.

Microsoft-Specific Modifiers
Modifiers specific to Microsoft C++. Memory addressing, calling conventions, naked functions, extended storage-class attributes (__declspec), __w64.

Inline Assembler
Using assembly language and C++ in __asm blocks.

Compiler COM Support
A reference to Microsoft-specific classes and global functions used to support COM types.

Microsoft Extensions
Microsoft extensions to C++.

Nonstandard Behavior
Information about nonstandard behavior of the Visual C++ compiler.

Component Extensions for Runtime Platforms
Reference material on using Visual C++ to target the common language runtime.

C/C++ Building Reference
Compiler options, linker options, and other build tools.

C/C++ Preprocessor Reference
Reference material on pragmas, preprocessor directives, predefined macros, and the preprocessor.

Visual C++ Libraries
A list of links to the reference start pages for the various Visual C++ libraries.
