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 
[work@db-testing-com06-vm3.db01.baidu.com 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
