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 usingastack? I am using avectorvector<char>as a stack here. ...

Input:(A+B)*C+(D-E)/F+G Output:AB+C*DE-F/+G+ Practice this problem The idea is to use thestack data structureto convert an infix expression to a postfix expression. The stack is used to reverse the order of operators in postfix expression. The stack is also used to hold operator...

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...
