size

Syntax:

    #include <deque>
    size_type size() const;

The size function returns the number of elements in the current deque.

For example:

    deque<int> myints;
    cout << "initial size: " << myints.size() << '\n';
 
    for( int i = 0; i < 5; ++i ) myints.push_back(i);
    cout << "after five additions: " << myints.size() << '\n';
 
    myints.insert( myints.begin(), 5, 100 );
    cout << "after five insertions: " << myints.size() << '\n';
 
    myints.pop_back();
    cout << "after a removal: " << myints.size() << '\n';

The above code produces the following output:

    initial size: 0
    after five additions: 5
    after five insertions: 10
    after a removal: 9
