Oct 21, 2012 · a+b-c+d; a/b+d; b * a-d+c; I am trying to do a postfix(or even infix) calculator, but cannot figure out where to start. I thought using a Stack implementation of a postfix(or infix) calculator would be good. I have been unable to find an appropriate website to help guide me in the correct direction. So some examples would be great. # Postfix calculator in c

3.9. Infix, Prefix and Postfix Expressions¶. When you write an arithmetic expression such as B * C, the form of the expression provides you with information so that you can interpret it correctly.

RPN is another name for postfix. Algebraic is another name for infix. The beauty of RPN is that you don't need parentheses. You instead have to enter operators and operands in the proper order. But you need a large enough stack. > I can follow the normal way of putting which is 5 ENTER 3 ENTER +.

- Operators that are in the same cell (there may be several rows of operators listed in a cell) are evaluated with the same precedence, in the given direction. For example, the expression a = b = c is parsed as a = (b = c), and not as (a = b) = c because of right-to-left associativity. Notes. Precedence and associativity are independent from ...

- Postfix Calculator. Postfix is an expression in which the operands are placed before their operators. There are no precedence rules, no parentheses needed. For example, 11 9 - is equal to 11 - 9 in the infix notation. It's much easier to calculate postfix expression by using the stack data structure.
