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( );
Remarks
备注
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.
Example
// 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 ;
}
}
Output
The output is:
1
2
3
The output is:
1
2
The output is:
