  2. Parameter (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Parameter_(computer...

    The specification for pass-by-reference or pass-by-value would be made in the function declaration and/or definition. Parameters appear in procedure definitions; arguments appear in procedure calls. In the function definition f(x) = x*x the variable x is a parameter; in the function call f(2) the value 2 is the argument of the function. Loosely ...

  3. C++14 - Wikipedia

    en.wikipedia.org/wiki/C++14

    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;.

  4. Syntactic sugar - Wikipedia

    en.wikipedia.org/wiki/Syntactic_sugar

    The reference to the object is passed as a hidden argument, usually accessible from within the method as this. A parameter called by reference is syntactic sugar for technically passing a pointer as the parameter, but syntactically handling it as the variable itself, to avoid constant pointer de-referencing in the code inside the function.

  5. Function (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Function_(computer...

    This function requires C++ – would not compile as C. It has the same behavior as the preceding example but passes the actual parameter by reference rather than passing its address. A call such as addTwo(v) does not include an ampersand since the compiler handles passing by reference without syntax in the call.

  7. First-class function - Wikipedia

    en.wikipedia.org/wiki/First-class_function

    C++ C++11 closures can capture non-local variables by copy construction, by reference (without extending their lifetime), or by move construction (the variable lives as long as the closure does). The first option is safe if the closure is returned but requires a copy and cannot be used to modify the original variable (which might not exist any ...

  8. Function pointer - Wikipedia

    en.wikipedia.org/wiki/Function_pointer

    A function pointer, also called a subroutine pointer or procedure pointer, is a pointer referencing executable code, rather than data. Dereferencing the function pointer yields the referenced function, which can be invoked and passed arguments just as in a normal function call.

  9. Input/output (C++) - Wikipedia

    en.wikipedia.org/wiki/Input/output_(C++)

    For example, basic_fstream<CharT,Traits> refers to the generic class template that implements input/output operations on file streams. It is usually used as fstream which is an alias for basic_fstream<char,char_traits<char>> , or, in other words, basic_fstream working on characters of type char with the default character operation set.
