示例1: tree_traversal_main
//int main( void )
int tree_traversal_main()
{
Tree* tree = new Tree();
tree->AddNode( 30 );
tree->AddNode( 10 );
tree->AddNode( 20 );
tree->AddNode( 40 );
tree->AddNode( 50 );
cout << "In order traversal" << endl;
tree->InOrder( tree->Root( ) );
cout << endl << endl;
cout << "Pre order traversal" << endl;
tree->PreOrder( tree->Root( ) );
cout << endl << endl;
cout << "Pre order traversal - no recursion" << endl;
tree->PreOrder_NoRecursion( tree->Root( ) );
cout << endl << endl;
cout << "Post order traversal" << endl;
tree->PostOrder( tree->Root( ) );
cout << endl << endl;
cout << "Tree Height : " << tree->Height( tree->Root() ) << endl;
cout << endl << endl;
delete tree;
return 0;
}示例2: main
int main()
{
Tree tree;
RandGen rg;
int i = 0;
while (i < 100)
{
if (tree.Insert(rg(100) - 50))
{
++i; //Need a tree Transversal (display) "pre order" "post order"
}
}
//TRANSVERSAL OUTPUTS ******ROOT IS BEGGINING OF PRE AND END OF POST*********
