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-

Write a program write a program called "infix.cpp", that uses a stack to convert a postfix expression to the corresponding fully-parenthesized infix expression. Consider the following examples: the postfix expressiona b + c d - *will be converted to the infix((a + b) * (c - d)) the...

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. ...
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...
Postfix expressions are evaluated strictly from left to right, using a stack to hold unprocessed operands and intermediate values. The method is simple. Tokens are read one at a time, starting from the left-hand side of the expression. If the token is an operand, we push it on to the st...
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. ...
