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. ...

Using the Tokens from above I convert to RPN format and than return the RPNReturnValues. Which can then be used to display the RPN string. public RPNReturnValues Convert(string InfixNotationToConvert, bool ReturnLatex) { RPNReturnValues retval = new RPNReturnValues(); retval.Error = ""; re...
