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...

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. The following is my code: #include<iostream>#include<...

1. Conversion from Infix to Postfix Notation Supported Mathematical Operators: +, - (unary and binary) *, /, ^ Supported Functions: sin, cos, tan, cot, sqrt, ln, exp Supported Constants PI Description: The expression is converted using a stack for operators. 2. Evaluation of Postfix Ex...
6. Conversion of Infix to Postfix One of the applications of postfix notation is to build a calculator or evaluate expressions in a programming language. In addition, we can evaluate postfix expressions efficiently using a stack data structure. ...
