Q. Write down an algorithm to evaluate an expression given to you in postfix notation. Show the execution of your algorithm for the following given expression.
AB^CD-EF/GH+/+*
Ans.
Algorithm to evaluate Post fix Expression is shown as follows
Opndstk = the empty stack;
/*scan the input string reading one */
/*element at a time into symb */
while ( not end of input){
symb = next input character;
if (symb is an operand)
push (opndstk, symb);
else
{
/* symb is an operator */
opnd 2 = Pop (opnd stk);
opnd 1 = Pop (opnd stk);
value = result of applying symb to opnd 1 and opnd 2;
push (opndstk,value);
}/*end else */
}/*end while */
return (pop (opnd stk));
