sorting - Print struct inputs in alphabetic order C++ -

i want print strings struct in alphabetic order, , have got thread how alphabetically sort strings?, sorting. problem when run compiler sorted output includes name struct. code looks this:

#include <iostream> #include <set> #include <algorithm> #include <string> using namespace std;  const int antalshops = 2; const int antalworkers = 5;  struct employ {      string workername; int workerage;  };  struct themall{     string shopname; string shoptype; int shopsize;      employ workername; employ workerage;  };  // declaration of structs themall shops[antalshops] = {     {"gamestop","toy", 250,},      {"frandsen", "cloth", 300,}, };  employ workers[antalworkers] = {     {"andrea valente", 41},      {"giovanni pirolli", 25},      {"marco cipolli", 33},     {"jensine jensen", 19},      {"andrea jensen", 99}, };  // functions sorting , printing names void print(const string& item) {     cout << item << endl; }  void printworkers(employ workers[]) {     set<string> sortedworkers;     for(int = 0; <= antalworkers; ++i) {         sortedworkers.insert(workers[i].workername);     }     for_each(sortedworkers.begin(), sortedworkers.end(), &print); }  void printshops(themall shops[]) {     set<string> sortedshops;     (int = 0; <= antalshops; ++i) {         sortedshops.insert(shops[i].shopname);     }     for_each(sortedshops.begin(), sortedshops.end(), &print); }  int main(int argc, const char * argv[]) {     printshops(shops); } 

so have structs workers , shops, when i try printing shop names printshops(shops) function output:

andrea valente frandsen gamestop 

i have been looking through code, can't find mistake is, can see error?

you go outside bounds of arrays in loops

for (int = 0; <= antalshops; ++i) { //   problem here ^^ 

the above loop loop on indexes 0, 1 and 2, 1 many two-entry array. lead undefined behavior.

you have same problem other sorting loop.
