c++ - Convert Vector<int> to String -

i want make program first input array of string, convert integer, , push vector.

the code :

string a; vector<long long int> c; cout << "enter message = "; cin >> a;    cout << endl;  cout << "converted message integer = "; (i=0;i<a.size();i++)  {     x=(int)a.at(i);     cout << x << " "; //convert every element string integer     c.push_back(x); } 

the output :

enter message = haha converted message integer = 104 97 104 97 

then write in file, , on next program want read back, , convert string, question how that? convert vector [104 97 104 97] string "haha".

i appreciate helps. thanks.

 std::vector<int> data = {104, 97, 104, 97}; std::string actualword; char ch; (int = 0; < data.size(); i++) {      ch = data[i];      actualword += ch;  }
