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<...

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 stack. If priority is greater, then push operator into operator stack. Otherwise pop two operands...
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...
