We have given an Arithmetic Expression and we have to write a program that converts the infix to postfix using stack in C. The Expression will be given in the form of a string, where alphabetic characters i.e a-z or A-Z denotes operands and operators are ( +, –, *, / ). Expres...

Infix to postfix 用stack模板,表达式没有括号 #include<stack> #include<iostream> #include<string> using namespace std; //优先级判断 char compare(char opt, char si) { if((opt=='+'||opt=='-')&&(si=='*'||si=='/') return '<'; else if(opt=='#') return '<'; return '>'; }...
Mathematical formulas are often made more accessible by using parenthesis. However, in computers,expressionswith multiple parentheses can be inefficient. So, mathematicians have created different notations such as infix, prefix, and postfix expressions to reduce computational work. In this tutorial, we’l...

I have written a C++ program to convert an infix expression to postfix expression using recursion. I would like to know if it can be improved if possible. Can we improve it by not using stack? I am using a vector as a stack here. ...
I need to write a program that reads a file as input and converts prefix to postfix and infix.. I wanted to know if I should do this using trees or think of an algorithm to convert it .. Sep 21, 2008 at 12:15am helios (17607) You mean these three? http://en.wikipedia.org/...
INFIX, PREFIX, & POSTFIX EXPRESSIONS. Infix Notation We usually write algebraic expressions like this: a + b This is called infix notation, because the. AdvertisementsRossella Lau Lecture 12, DCO20105, Semester A, DCO Data structures and algorithms Lecture 12: Stack and Expression Evaluation...

To convert infix expression to postfix expression, we will use the stack data structure. By scanning the infix expression from left to right, when we will get any operand, simply add them to the postfix form, and for the operator and parenthesis, add them in the stack maintaining the preced...
