class X {
};
inline X::X()
{
cout << "X" << endl;
}
1) is "inline" keyword required or optional here?
2) will compiler always "inline" this function if "inline" keyword exists?
3) will compiler always skip "inline" this function if "inline" keyword
doesn't exists?
4) if 2) & 3) both "no", then why we need inline keyword? | t****t

otherwise it's multiple definition. inline members can be multiple defined,
even if it is not always inlined.
2. no
3. no
4. see answer to 1.
