In computer programming, an anonymous function (function literal, expression or block) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function. [ 1 ]
The rules are effectively the same as inline functions __has_include, allowing the availability of a header to be checked by preprocessor directives [25] Value of __cplusplus changed to 201703L [26] Exception specifications were made part of the function type [27] Lambda expressions can capture "*this" by value [28]
In fact computability can itself be defined via the lambda calculus: a function F: N → N of natural numbers is a computable function if and only if there exists a lambda expression f such that for every pair of x, y in N, F(x)=y if and only if f x = β y, where x and y are the Church numerals corresponding to x and y, respectively and = β ...
Any member function of a class, such as copy constructors, operator overloads, etc., can be declared as constexpr, so long as they meet the requirements for constexpr functions. This allows the compiler to copy objects at compile time, perform operations on them, etc. If a constexpr function or constructor is called with arguments which aren't ...
C++11 allowed lambda functions to deduce the return type based on the type of the expression given to the return statement. C++14 provides this ability to all functions. It also extends these facilities to lambda functions, allowing return type deduction for functions that are not of the form return expression;.
The functions vary, however, according to the program you’re in. (For example, in an email program, F9 will check for new mail. In Microsoft Word, it will refresh your document.)
