Thread: inlined and outlined member functions

I dunno if there is a typo in my C++ book or not, but I was wondering how a inlined and outlined function would be declared and defined in a class. If possible, put why it is good to inline and outline functions and why it's not.

Thanks.

Inline functions are good for performance reasons, normally when you call a function a jump occurs in the code which creates some [minor] ovehead. Inlining is good when the function is trivial (one liners, getters, setters, etc.), or it can be good if you have performance problems. Lastly, the compiler may not inline your method, it may put in code for a function call anyway.

You can do inlining nice like this:

Code:

class X {
public:
    void foo( );
};

inline void X::foo( ) {
    cout << "hello from foo\n";
}

Any function not inlined is "outlined" I suppose.
