deque::push_back and deque::pop_back 

Illustrates how to use the deque::push_back and deque::pop_back Standard Template Library (STL) functions in Visual C++.


void push_back(
   const T& x
);
void pop_back( );

NoteNote

The class/parameter names in the prototype do not match the version in the header file. Some have been modified to improve readability.

The push_back function inserts an element with value x at the end of the container deque. The pop_back function removes the last element of the container deque, which must be nonempty.

// pushback.cpp
// compile with: /EHsc

#include <iostream>
#include <deque>

using namespace std;


typedef deque<int >  INTDEQUE;
void printcontents (INTDEQUE  deque);

int main()
{

    INTDEQUE  dequetest;

    dequetest.push_back(1);
    dequetest.push_back(2);
    dequetest.push_back(3);
    printcontents (dequetest);
    dequetest.pop_back();
    printcontents (dequetest);
    dequetest.pop_back();
    printcontents (dequetest);
   }

   //function to print the contents of deque
   void printcontents (INTDEQUE  deque)
   {
       INTDEQUE::iterator pdeque;

       cout <<"The output is:"<<endl;

           for(pdeque = deque.begin();
           pdeque != deque.end();
           pdeque++)
       {
           cout << *pdeque <<endl ;
       }
   }

The output is:
1
2
3
The output is:
1
2
The output is:
1
