Infix notation is the common arithmetic and logical formula notation, in which operators are written infix-style between the operands they act on (e.g. 2 + 2). It is not as simple to parse by computers as prefix notation ( e.g. + 2 2 ) or postfix notation ( e.g. 2 2 + ), but many programming languages use it due to its familiarity. In infix notation, unlike in prefix or postfix notations, parentheses surrounding groups of operands and operators are necessary to indicate the intended order in which operations are to be performed. In the absence of parentheses, certain precedence rules determine the order of operations. From Wikipedia under the

Q. how can i recognise the infix and postfix notation using C++ stacks data structure? Asked by khak - Mon May 19 07:30:50 2008 - - 2 Answers - 0 Comments A. If, after parsing, the item on the top of the stack is an operator then postfix is used; otherwise it's infix. That is of course assuming it's either one or the other.

Q. i have a class called infix and a seperate class called postfix. what i am trying to do is make the infix class create a string of postfix notation and then call the postfix class to do the computation. i have the string all ready to be passed to the postfix class for computation..my question is...how do i get it to that class?

Q. please help me to answer write this program!...thankz! write a program that implements the infix to postfix notation. The program should read an infix string consisting of single alphabetic characters for variables,parenthesis and the , - , * and / operators,call the conversion algorithm and then print the resulting postfix expression after transforming an algorithm,it should loop and convert another infix string.. Asked by chel - Tue Aug 5 02:58:24 2008 - - 1 Answers - 0 Comments A. This sounds like homework. I won't help with code, however let's talk about design. Let's start with what an infix expression is: Any expression in the standard form like: b*c+d or like b+c*d or something complex like a+(b+c*d)*e We want to end up with an output in postfix (also known as Polish Notation): bc*d+ or like bcd*+ or somethign complex like abcd*+e*+ I would look up postfix (polish) notation if you don't already know this. So now, how do we do this? Well, if parenthesis weren't it would probably be easier. Let's think about this case first. Initialise an empty stack. For each character in the infix string identify it: -If the scannned character is an operand, add it immediately to the Postfix string. -If the… [cont.] Answered by janusmccarthy - Tue Aug 5 05:54:43 2008 From Yahoo Answer Search: "infix notation"  news.google.com Genc Medya ESBCalc is a Freeware Win32 Scientific Calculator with Infix Notation , Brackets, Scientific Functions, Memory, Optional Paper Trail, Result History List, ...
