I am implementing a binary tree and now I want to write a method that deletes the tree. Can I simply call "delete this;" in my method? Here's the code: //don't care about instruction_name and clip_index struct Instruction{ Instruction * left_child, * right_child; int instruction_name; int clip_index; bool operator<(Instruction & i) {return (instruction_name < i.instruction_name);} bool operator<(int name) {return (instruction_name < name);} void Print(int level) { std::cout << "Level: " << level << " Inst_Name: " << instruction_name << " Clip_Index: " << clip_index << '\n'; ++level; if(left_child) left_child->Print(level); if(right_child) right_child->Print(level); } void CopyTree(Instruction ** root){ (*root) = new Instruction(instruction_name,clip_index); if(left_child) left_child->CopyTree(&(*root)->left_child); if(right_child) right_child->CopyTree(&(*root)->right_child); } void DeleteTree(){ if(left_child) left_child->DeleteTree(); if(right_child) right_child->DeleteTree(); std::cout << "Node deleted!\n"; delete this; // will this cause any problems? } Instruction(int name, int clip) {left_child = right_child = 0; instruction_name = name; clip_index = clip;} }

yeah, the heap/stack - thing is good to know. It's somewhat clear, but you could easily forget about that, thanks. I didn't write a copy constructor, because I don't need one. I will only use this class once.
