deque::begin and deque::end
Illustrates how to use the deque::begin and deque::end Standard Template Library (STL) functions in Visual C++.
const_iterator begin( ) const;
iterator begin( );
const_iterator end( ) const;
iterator end( );
Remarks
注意
The class/parameter names in the prototype do not match the version in the header file. Some have been modified to improve readability.
The begin member function returns a random-access iterator that points at the first element of the sequence or just beyond the end of an empty sequence. The end member function returns a random-access iterator that points just beyond the end of the sequence.
Example
// begin.cpp
// compile with: /EHsc
//
// Functions:
//
// begin()
// end()
#include <iostream>
#include <deque>
using namespace std;
typedef deque<int > INTDEQUE;
int main()
{
// Create A and fill it with elements 1,2,3,4 and 5
// using push_back function
INTDEQUE A;
A.push_back(1);
A.push_back(2);
A.push_back(3);
A.push_back(4);
A.push_back(5);
// Print the contents of A using iterator
// and functions begin() and end()
INTDEQUE::iterator pi;
for(pi= A.begin(); pi !=A.end(); pi++)
{
cout << *pi <<" " ;
}
cout<<endl;
}
Output
1 2 3 4 5
