Sure the 16-cell battery weighs a pound more than the 8-cell battery, but this is for patients that donât mind a little additional weight tacked onto their G3 in exchange for a longer time with friends and family without running out of oxygen.
An explicit definition of a function f gives an algorithmic procedure, usually given by an algebraic formula, that produces the output (dependent variable) of f for a given input (independent variable); for example, f(x) = x2.
A constructor with a single non-default parameter (until C++11) that is declared without the function specifier explicit is called a converting constructor. Both constructors (other than copy/move) and user-defined conversion functions may be function templates; the meaning of explicit doesn't change.
