Answer #1

a)

The infix expression is given as;

(a + b) * (c - d) / (e + f)

b)

/, postorder(*), /
*, postorder(+), * /
+, postorder(a), + * /
a, postorder(b), a + * /
b, postorder(-), a b + * /
-, postorder(c), a b + - * /
c, postorder(d), a b + c - * /
d, postorder(+), a b + c d - * /
+, postorder(e), a b + c d - * + /
e, postorder(f), a b + c d - * e + /
f, -, a b + c d - * e f + /

(a) Provide the ordinary infix expression represented by this tree. (b) Trace the sequence of events for calling function postorder on the root of this expression tree. The function uses a leftmost- child-right sibling representation of void postorder (PNODE n) nodes in an expression tree. The label of { an interior node is the arithmetic PNODE C; /* a child of node n */ operator and the label of a leaf is the (1) C-n->leftmost Child; (2) numerical value of...

Infix Expression Evaluator For this project, write a C program that will evaluate an infix expression. The algorithm REQUIRED for this program will use two stacks, an operator stack and a value stack. Both stacks MUST be implemented using a linked list. For this program, you are to write functions for the linked list stacks with the following names: int isEmpty (stack); void push (stack, data); data top (stack); void pop (stack); // return TRUE if the stack has no...

Write a parser program for cSub using the method of recursive descent. The main program here will effectively be the main program of the compiler as a whole. The input to the program will be a Csub source file, specified on the command line. The program will construct a parse tree for the program, with one interior node for every nonterminal in the derivation of the program, and one leaf node for each of the id, num, and real tokens...
