Keywords in C++
The keywords implement specific C++ language feature. They are explicitly reserved identifiers and cannot be used as names for the program variables or other user-define program elements.
Asm
|
To declare that a block of code is to be passed to the assembler
|
Auto
|
A storage class specifier that is used to define objects in a block
|
Bool
|
Boolean false-true type that can hold either the false or true literals
|
Break
|
Terminates a switch statement or a loop
|
Case
|
Used specifically within a switch statement to specify a match for the statement's expression
|
Catch
|
Specifies actions taken when an exception occurs
|
Char
|
Fundamental data type that defines character objects
|
Class
|
To declare a user-defined type that encapsulates data members and operations or member functions
|
Const
|
To define objects whose value will not alter throughout the lifetime of program execution
|
Const_Cast
|
const_cast is used to cast away the constness of variables.
|
Continue
|
Transfers control to the start of a loop
|
Default
|
Handles expression values in a switch statement that are not handled by case
|
Delete
|
Memory deallocation operator
|
Do
|
Indicates the start of a do-while statement in which the sub-statement is executed repeatedly until the value of the expression is logical-false
|
Double
|
Fundamental data type used to define a floating-point number
|
Dynamic_Cast
|
The
dynamic_cast keyword casts a datum from one pointer or reference type to another, performing a runtime check to ensure the validity of the cast |
Else
|
Used specifically in if-el.se statement
|
Enum
|
To declare a user-defined enumeration data type
|
Explicit
|
To declare an explicit constructor
|
Export
|
Allows a template definition to be accessible from another translation unit.
|
Extern
|
An identifier specified as extern has external linkage to the block
|
False
|
Boolean literal of value zero
|
Float
|
Fundamental data type used to define a floating-point number
|
For
|
Indicates the start of a for statement to achieve repetitive control
|
For
|
A class or operation whose implementation can access the private data members of a class
|
Goto
|
Transfer control to a specified label
|
If
|
Indicate start of an if statement to achieve selective control
|
Inline
|
A function specifier that indicates to the compiler that inline substitution of the function body is to be preferred to the usual function call implementation
|
Int
|
Fundamental data type used to define integer objects
|
Long
|
A data type modifier that defines a 32-bit int or an extended double
|
Mutable
|
Allows an object member to override constness
|
Namespace
|
Defines a scope
|
New
|
Memory allocation operator
|
Operator
|
Overloads a c++ operator with a new declaration
|
Private
|
Declares class members which are not visible outside the class
|
Protected
|
Declares class members which are private except to derived classes
|
Public
|
Declares class members which are visible outside the class
|
Register
|
A storage class specifier that is an auto specifier, but which also indicates to the compiler that an object will be frequently used and should therefore be kept in a register
|
Return
|
Returns an object to a function's caller
|
Short
|
A data type modifier that defines a 16-bit int number
|
Signed
|
A data type modifier that indicates an object's sign is to be stored in the high-order bit
|
Sizeof
|
Returns the size of an object in bytes
|
Static
|
The lifetime of an object defined static exists throughout the lifetime of program execution
|
Struct
|
To declare new types that encapsulate both data and member functions
|
Switch
|
Switch statement
|
Template
|
Parametrised or generic type
|
This
|
A class pointer which points to an object or instance of the class
|
Throw
|
Generate an exception
|
True
|
Boolean literal of value one
|
Try
|
Indicates start of a block of exception handlers
|
Typedef
|
Synonym for another integral or user-defined type
|
Typeid
|
The typeid () operator returns the type of its operand
|
Typename
|
Within a template typename indicates that a qualified name denotes a type
|
Union
|
Similar to a structure, struct, in that it can hold different types of data, but a union can hold only one of its members at a given time.
|
Unsigned
|
A data type modifier that indicates the high-order bit is to be used for an object
|
Using
|
using declaration and using directive
|
Virtual
|
A function specifier that declares a member function of a class which will be redefined by a derived class
|
Void
|
Absent of a type or function parameter list
|
Volatile
|
Define an object which may vary in value in a way that is undetectable to the compiler
|
Wchar_t
|
Wide character type
|
While
|
Start of a while statement and end of a do-while statement
