{return (ctr==1)?word:word+ending;
}int main()
{cout<<"Singular version: "<<make_plural(1,"success","es")//success单数<<"\tplural version: "<<make_plural(0,"success","es")<<endl           //success复数<<"Singular version: "<<make_plural(1,"failure")        //failure单数<<"\tplural version: "<<make_plural(0,"failure")<<endl;              //failure复数return 0;
}
