c++ - Input not being put in through out Vector -


okay, trying read input vector, print out in reverse order. have pretty idea of how ( think) problem code reads user input first slot of vector. . . need read 10 separate strings input 10 different slots in vector. . . here i've got far:

#include <iostream>; #include <vector>; #include <string>;  using namespace std;  int main() {     vector<string> name_list(11);     int n = 0;     (int n = 0; n < 11; ++n);     getline(cin, name_list[n]);     cout << name_list[0];      int stop;     cin >> stop;     return 0; } 

you have semicolon after loop statement

for (int n = 0; n < 11; ++n); 

so loop nothing

also speaking 10 elements need read.

the code following way:

const size_t n = 10; vector<string> name_list( n );  ( int n = 0; n < n; ++n ) {     getline( cin, name_list[n] ); }  ( vector<string>::size_type n = name_list.size(); n != 0; ) {      cout << name_list[--n] << endl; } 

also same can written using standard algorithms. example

const size_t n = 10; vector<string> name_list;  name_list.reserve( n );  copy_n( istream_iterator<string>( cin ), n, back_inserter( name_list ) );  reverse_copy( name_list.begin(), name_list.end(), ostream_iterator<string>( cout, "\n" ) );
