Faculty of Computer Science and Engineering Department of Computer Science LAB SESSION 3 RECURSION on BINARY TREE 1. OBJECTIVE The objectives of Lab 3 are (1) to introduce an implementation of binary tree in C++ and (2) to practice recursion algorithms to manipulate a tree. 2. FILE-LEVEL SEPARATION of INTERFACE and IMPLEMENTATION Class interface and implementation In Lab 2, we have learnt about the concept of separation between the interface and the implementation of a class. In practice, the separation is implemented as the file-level, . we store the interface and the implementation in different files, whose extensions are respectively.
