Consider the following function declarations from the definition of the

class Money in Display 11.4.

void input(istream& ins);

void output(ostream& outs) const;

Rewrite these function declarations so that they do not need to be preceded by

using namespace std;

(You do not need to look back at Display 11.4 to do this.)
