我正在使用二叉搜索树。在这里,我正在编写一个函数来从树中删除一个项目。在以下代码中:
if(root = NULL)//if there is nothing in the tree
{
cout<<"the Tree is empty"<<endl;//ouput to the screen
return;//exit the function
}
bool isFound = false;//tells us if the item is found
Node* tmp = new Node();//declare a temp pointer
Node* tmp2 = new Node();;//declare a temp pointer
tmp* = *root;//assign the pointer to something
它正在调用复制构造函数,但正如我现在所拥有的那样,我只是复制这样的值:
Node& Node::operator= (const Node& node)
{
data = node.data;
left = node.left;
right = node.right;
return *this;
}
