代碼：#include <iostream>#include <string>#include <vector>#include <cctype>using std::cin;using std::cout;using std::endl;using std::string;using std::vector;int main(){vector<string> s;string word;while(cin >> word ){s.push_back(word);}for (auto word:s)cout << toupper(word) << endl;return 0;}用的是g++編譯器，版本4.9.3謝謝你的幫助??！
