C++Primer Plus（第六版） 第十六章 第八题

这主要是STL的使用，之前书看的比较认真的话基本没什么问题

#include <iostream>#include <set>#include <algorithm>#include <iterator>#include <cstdlib>#include <string>int main(){std::string temp;std::set<std::string> Mats;std::cout << "Enter Mat's guest list (empty line to quit):\n";while (std::getline(std::cin, temp) && temp.size() > 0)Mats.insert(temp);std::ostream_iterator<std::string, char> out(std::cout, "\n");std::cout << "Mat's guest list:\n";copy(Mats.begin(), Mats.end(), out);std::set<std::string> Pats;std::cout << "Enter Pat's guest list (empty line to quit):\n";while (std::getline(std::cin, temp) && temp.size() > 0)Pats.insert(temp);std::cout << "\nPat's guest list:\n";copy(Pats.begin(), Pats.end(), out);std::set<std::string> Both;set_union(Mats.begin(), Mats.end(), Pats.begin(), Pats.end(),std::insert_iterator<std::set<std::string> >(Both, Both.begin()));std::cout << "\nMerged guest list:\n";copy(Both.begin(), Both.end(), out);std::cin.get();return 0;}
