Example details of C++ list

Source:

#include <iostream>
#include <list>
#include <numeric>
#include <algorithm>
using namespace std;

typedef list<int> LISTINT;  // create 1 a list Instances of containers LISTINT
typedef list<int> LISTCHAR; // create 1 a list Instances of containers LISTCHAR
int main(void) {
  LISTINT listOne;  // with LISTINT create 1 called listOne the list object
  LISTINT::iterator i;  // The statement i For the iterator
  listOne.push_front (2); // Once upon a time for listOne Add data to the container
  listOne.push_front (1);
  listOne.push_back (3); // From the face listOne Add data to the container
  listOne.push_back (4);

  cout<<"listOne.begin()--- listOne.end():"<<endl;  // Front to back listOne The data in the
  for (i = listOne.begin(); i != listOne.end(); ++i)
    cout << *i << " ";
  cout << endl;

  LISTINT::reverse_iterator ir;  // Display from the back to the back listOne The data in the
  cout<<"listOne.rbegin()---listOne.rend():"<<endl;
  for (ir =listOne.rbegin(); ir!=listOne.rend();ir++)
    cout << *ir << " ";
  cout << endl;

  int result = accumulate(listOne.begin(), listOne.end(),0); // use STL the accumulate( cumulative ) algorithm
  cout<<"Sum="<<result<<endl;

  LISTCHAR listTwo;  // with LISTCHAR create 1 called listOne the list object
  LISTCHAR::iterator j;   // The statement j For the iterator
  listTwo.push_front ('A'); // Once upon a time for listTwo Add data to the container
  listTwo.push_front ('B');
  listTwo.push_back ('x');  // From the face listTwo Add data to the container
  listTwo.push_back ('y');
  cout<<"listTwo.begin()---listTwo.end():"<<endl; // Front to back listTwo The data in the
  for (j = listTwo.begin(); j != listTwo.end(); ++j)
    cout << char(*j) << " ";
  cout << endl;
  // use STL the max_element Algorithm for listTwo The largest element in and displays
  j=max_element(listTwo.begin(),listTwo.end());
  cout << "The maximum element in listTwo is: "<<char(*j)<<endl;
  return 0;
}

Result:

[work@db-testing-com06-vm3.db01.baidu.com c++]$ g++ -o list list.cpp
[[email protected] c++]$ ./list
listOne.begin()--- listOne.end():
1 2 3 4
listOne.rbegin()---listOne.rend():
4 3 2 1
Sum=10
listTwo.begin()---listTwo.end():
B A x y
The maximum element in listTwo is: y
