Could you list the main method specifiers in programming languages?

In C and C++ languages, method (function) specifiers define the scope, behavior, and properties of functions. Main specifiers:

• static — limits the visibility of the function to the current file (in C) or makes the class method static (in C++).
• extern — indicates that the function is defined elsewhere (commonly used in C).
• inline — suggests to the compiler to embed the function instead of calling it for optimization.
• virtual (only in C++) — allows methods to be overridden in derived classes, supporting polymorphism.
• const (in C++) — indicates that the method does not modify the state of the object.
• friend (C++) — allows a function or class to access private members of the class.

Example in C++:

class MyClass {
public:
    static void staticMethod(); // static method
    virtual void virtualMethod(); // virtual method
    void constMethod() const; // method that does not modify the object
};

In C, function specifiers are usually limited to static, extern, and inline.
