Question

write a program that takes as input an infix expression and

outputs the equivaqlent post fix expression.

here are the details..

1) Ask the user to input an arithmetic expression in infix

notation. The

expression may contain integers, operators, parenthesis and

variables.

There should be a space between each item in your input

expression.

2) Convert the expression to postfix notation,

You are required to use at least one

stack

to create the expression

3) Your input expression should contain only positive

integers

4) If the expression entered is not well formed, your program

should

issue an error message telling the user that their input is in

error, and

ask for another expression to evaluate (flush your stack!)

5) Write your code to use a loop that allows the user to enter

moreÂ

expressions until they indicate that they are finished.

6) Extra Credit: using no variables in your input expression,

only

integers and operators,†¦create the

corresponding postfix expression,

print it, and then correctly evaluate the postfix

expression.
