サンプルコード

#include <iostream>
#include <list>
#include <string>
#include <cstdlib>
using namespace std;
int main() {
   list<int> l;
   list<int>::iterator it;
   int c, i;
   while (1) {
      cout<<"1.Insert Element to the list"<<endl;
      cout<<"2.Display the List"<<endl;
      cout<<"3.Exit"<<endl;
      cout<<"Enter your Choice: ";
      cin>>c;
      switch(c) {
         case 1:
            cout<<"Enter value to be inserted";
            cin>>i;
            l.push_back(i);
         break;
         case 2:
            l.sort();
            cout<<"Elements of the List: ";
            for (it = l.begin(); it != l.end(); it++)
               cout<<*it<<" ";
            cout<<endl;
         break;
         case 3:
            exit(1);
         break;
         default:
            cout<<"Wrong Choice"<<endl;
      }
   }
   return 0;
}
