Method prototype

• cppreference.com - Declaring functions

The precedence rules are based on the following principles.

• Syntax closer to machine code comes first.
• Syntax that affects abstract concepts of the code or the programming itself comes later.

Applying the rules above produces the following.

1. Compiler-specific directives: keywords such as attributes (e.g. GCC's __attribute__((deprecated))).
2. Directives related to the final generated machine code: inline
3. Scope of effect on the program
   1. Compile time: constexpr
   2. Static code: explicit, static
   3. Dynamic code: virtual
4. Return value
5. Function name
6. C++11 Attribute: [[noreturn]], [[carries_dependency]]

The keyword order in C++ is as follows.

attributes inline constexpr static explicit virtual [return-type] const volatile [&/&&] Method [[c++11-attributes]] (arguments) const volatile [&/&&] [throw/noexcept] override

A (somewhat contrived) syntactically valid example is as follows.

struct Temp1
{
    int value = 0;
    __attribute__((deprecated)) inline virtual int const volatile & dep1() const volatile && noexcept((noexcept(Temp1())))
    { return value; }

    constexpr Temp1(){}
};

struct Temp : public Temp1
{
    int value = 0;
    constexpr Temp(){}
    constexpr explicit Temp(int v) : value(v){}

    __attribute__((deprecated)) inline virtual int const volatile & dep1 [[carries_dependency]] () const volatile && noexcept((noexcept(Temp()))) override
    { return value; }
    __attribute__((deprecated)) inline constexpr static int dep2()
    { return 1; }
};
