关于这个啊,你多用就好了,三种方法,你好好到c++ 官网去看看 http://www.cplusplus.com/reference/list/list/insert/

// inserting into a list
#include <iostream>
#include <list>
#include <vector>

int main ()
{
  std::list<int> mylist;
  std::list<int>::iterator it;

  // set some initial values:
  for (int i=1; i<=5; ++i) mylist.push_back(i); // 1 2 3 4 5

  it = mylist.begin();
  ++it;       // it points now to number 2           ^

  mylist.insert (it,10);                        // 1 10 2 3 4 5

  // "it" still points to number 2                      ^
  mylist.insert (it,2,20);                      // 1 10 20 20 2 3 4 5

  --it;       // it points now to the second 20            ^

  std::vector<int> myvector (2,30);
  mylist.insert (it,myvector.begin(),myvector.end());
                                                // 1 10 20 30 30 20 2 3 4 5
                                                //               ^
  std::cout << "mylist contains:";
  for (it=mylist.begin(); it!=mylist.end(); ++it)
    std::cout << ' ' << *it;
  std::cout << '\n';

  return 0;
}

http://www.cplusplus.com/reference/list/list/push_back/

// list::push_back
#include <iostream>
#include <list>

int main ()
{
  std::list<int> mylist;
  int myint;

  std::cout << "Please enter some integers (enter 0 to end):\n";

  do {
    std::cin >> myint;
    mylist.push_back (myint);
  } while (myint);

  std::cout << "mylist stores " << mylist.size() << " numbers.\n";

  return 0;
}

http://www.cplusplus.com/reference/list/list/push_front/ // list::push_front #include <iostream> #include <list> int main () { std::list<int> mylist (2,100); // two ints with a value of 100 mylist.push_front (200); mylist.push_front (300); std::cout << "mylist contains:"; for (std::list<int>::iterator it=mylist.begin(); it!=mylist.end(); ++it) std::cout << ' ' << *it; std::cout << '\n'; return 0; } 把这个网址收藏起来吧
