Standard Template Library

map

#include <map>
#include <iostream>

using std::map;
using std::cout;
using std::endl;

struct A {
  A(): _p(0) {
    cout<<"A::A()"<<endl;
  }
  A(int p): _p(p) {
    cout<<"A::A(int p)"<<endl;
  }
  A& operator=(A const& other) {
    _p=other._p;

    return *this;
  }
  int _p;
};

int main() {
  map<int,A> m;
  m[1]=A(42);
  m.insert(std::make_pair(4,A(11)));
  for(std::pair<int,A> p: m) {
    cout<<"m["<<p.first<<"]: "<<p.second._p<<'\n';
  }
  return 0;
}

• What is the output of this code, i.e. which constructors get called?
• What is the advantage of insert?
