Syntax:
    #include <queue>
    void push( const TYPE& val );
The function push() adds val to the end of the current queue.
For example, the following code uses the push() function to add ten integers to
the end of a queue:
     queue<int> q;
     for( int i=0; i < 10; i++ ) {
       q.push(i);
     }
