  It doesn't *have* to be (any more than any other function defined in a
header file, or anywhere else), but the standard says it is, and so it is.

  The difference can be seen eg. like this:

//-------- Example 1 ----------
class A
{
 public:
    // This function is implicitly 'inline',
    // no need to specify the keyword:
    void foo() { std::cout << "Hello\n"; }
};
//-----------------------------

//-------- Example 2 ----------
class A
{
 public:
    void foo();
};

// This function is *not* implicitly 'inline' and will cause linker
// errors unless the keyword is used:
void A::foo() { std::cout << "Hello\n"; }
//-----------------------------
