Can the method defined in source file be inlined?

For example

// a.h
strcut A
{
    void simpleMethod();
    void anotherMethod() {...; simpleMethod(); ...;}
};

// a.cpp
#include "a.h"
void A::simpleMethod() { one_line_simple_implementation; }

My question is: Can simpleMethod() be inlined in anotherMethod() by the modern compiler optimization?

you can use inline void A::simpleMethod() { ... } or you might get multiple definitions error if you don't use inline keyword. or you could just do 

class A
{
    void foo() { ... };
};

In this case, yes. if a.cpp includes a.h (I suppose so). As long as the compiler can see the full definition. it is fine. But you need to say so.

inline     void A::simpleMethod() { one_line_simple_implementation; }
