Illustrating the generic lexicographical_compare algorithm

#include <iostream> #include <cassert> #include <algorithm> #include <vector> using namespace std; int main() {   string s("helio");   string s2("hello");   vector<char> vector1(s.begin(), s.end());   vector<char> vector2(s.begin(), s.end());   // Show that vector1 is lexicographically less than vector2:   bool result = lexicographical_compare(vector1.begin(),vector1.end(), vector2.begin(), vector2.end());   cout << result;   return 0; } /*  0  */
