Practice 9.41

#include <iostream> #include <queue> #include <string> #include <vector> #include <algorithm> #include <list> #include <iterator> #include <cmath> #include <cstring> #include <forward_list> using namespace std;void init_string(vector<char> & chvec, string & str) {for(auto i : chvec) {str += string(&i,1);} } int main() {vector<char> chvec = {'j','i','n','h','a','i'};string res = "";init_string(chvec, res);cout << "Here's result: " << endl; cout << res << endl;return 0; }

Output

Here's result: jinhai

**A people which is able to say everything becomes able to do everything.
