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. ...

Prefix, Postfix, Infix Notation. Infix Notation To add A, B, we write A+B To multiply A, B, we write A*B The operators ('+' and '*') go in between. Stacks A stack is a linear data structure that can be accessed only at one of its ends for storing and ...

Popping Remaining Operators from the Stack: After traversing the entire string, remaining operators are popped from the stack and added to the postfix string. Example Usage of the infix_to_postfix Function Let's consider the algorithm's operation using the expression -2*ln(x)/(4*-2*sin(5*...
