[B]Expression evaluation using Emit[/B] This class was designed to evaluate simple mathematical expressions. But instead of developing a routine to do the calculating, we use Emit to dynamically build a method that does the math for us. IMPORTANT: This is done with integer math. 7/2*3 = 9, not 10.5 (or …

I am trying to transform a infix mathematical expression into a postfix expression using the shunting yard algortihm but can only get so far by writing the pseudo code because I know exactly what to do through logical thinking but can't write the code that will help me do it. …

Hi basically i need help , i am not good with c++ but i am trying my very best. i am currently stuck with trying to do an infix to postfix conversion that reads from a textfile. The text file contains the infix notations and the code is suppose to …

I am working on a project for class. I have to write a program that reads in an infix expression and converts and it to postfix and evaluates it. Currently I have it to where I can convert an infix expression with no parentheses to postfix, but am having some …

Hi, Please help me debug this code. I made a Stack template with two parameters: type and size. I am using it two times: first in conversion from infix expression to postfix (here, <char,50> stack is used), then in evaluation of postfix expression (here, <long double, 50> stack is used). …

i have problem in convert infix to postfix some expression evaluate it correctly and other no ex: c\*(a+b) evaluate it correctly but A\*(B\*C+D)+E doesn't evaluate correctly and there is another problem in finding result my code // convert.h const char SIZE=100; class stack { public: stack(); bool isempty()const; bool isfull()const; …

The program runs and gives the correct data until it gets to the 4th line of the input. At the 4th line, the calculation is incorrect and when it gets to line 6 of the input, it just stops completely. I can't quite figure it out. Any help is greatly …

hi i want to convert the prefix form to postfix,prefix and infix form but when i input +5*62 it retuns only 2 what is wrong with my code can anybody help to solve this #include<stdio.h> #include<conio.h> #include<stdlib.h> #define Operator 1 #define notOperator 0 #define empty -1 struct node{ char item; …

Hello community, I have an issued converting a arithmetic string called the infix, into a prefix output. In one of my methods i have an infinite loop. An example would be (a + b) * (c - d)===> * + a b - c d Here is my code: [CODE] …

Hi! I am trying to write calculator in c++ that takes an infix expression, converts it to postfix, and calculates. I have the code that will do this written, but when I try to turn it into a class it gives my a Segmentation Fault. Here is my code... [CODE=c++]//calc.h …

So basically I need to find a way to evaluate an infix that's been converted into a postfix. The code below takes an entered infix and converts it into a postfix but I don't know how to take that postfix and evaluate it. Every single tutorial I've seen evaluates a …

I need some idea how to correct this program. Though I think I understand the concept, my implementation is wrong. My program only prints the orignal string and does nothing with it. [CODE] public class ArrayStack<E> implements Stack<E> { protected int capacity; protected static final int CAPACITY = 1000; protected …

here's the infix expression: [B]EXAMPLE 1[/B] a/(b+c)*d according to me, if [B]*[/B] is given higher precedence then [B]/[/B] , then this should be the postfix expression: [B]1) abc+d*/ [/B] if / has higher priority then * , then: [B]2) abc+/d*[/B] [B]question 1: [/B]which is correct?? 1 or 2 ? according …

Hey, i know you are all probably very bored with the infix to postfix program and its many incarnations but i seem to be having a problem getting the linked list we have to use as a stack to work. More specifically; pushing to the stack, reading from the top …
