The C++ Standard Library by Nicolai M. Josuttis states:
There is a minor difference between
X x; Y y(x) //explicit conversion
X x; Y y = x; //implicit conversion
Following to say: "The former creates a new object of type Y by using an explicit conversion from type X, whereas the latter creates a new object of type Y by using an implicit conversion."
I'm a little confused about the concepts of explicit vs implicit conversion I guess. In both cases you're taking an X and pushing it into a Y per se – one uses a Y's constructor and one uses the assignment operator though.
What's the difference in how the conversion is treated in these two cases, what makes it explicit/implicit, and how does this tie into making a class constructor defined with the "explicit" key word, if at all?
