WebApr 14, 2015 · We can evaluate the postfix expression using the binary tree by keeping in mind the two conditions if eval (root) is an operator we use recursion, eval (root->llink) + eval (root->rlink) else we return root->info - '0' Function for evaluation WebBut it's the postfix notation needed by a stack-based calculator/processor. If you don't know what that is, don't worry about it. So if we build an expression tree, we can preorder/inorder/postorder traverse it to convert between prefix/infix/postfix notations. That's one of the reasons a compiler has to build that tree. philips hid headlights
