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 Prefix conversion using two stacks Infix: An expression is called the Infix expression if the operator appears in between the operands in the expression. Simply of the form (operand1 operator operand2). Example :(A+B) * (C-D) Prefix: An expression is called the prefix expression ...
6. Traverse the infix expression and check if given character is an operator or an operand. If it is an operand, then push it into operand stack. If it is an operator, then check if priority of current operator is greater than or less than or equal to the operator at top of the sta...
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/...
While infix expressions are common and intuitive for humans to read and write, prefix and postfix notations are computationally efficient and valuable for creating computer programs that manipulate expressions. In particular, we can easily evaluate the postfix expressions with a stack data structure, mak...
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...
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 usingastack? I am using avectorvector<char>as a stack here. ...

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...
