Infix To Postfix, is a Stack related problem and in this post we will see how we can solve this challenge in C++

Infix to postfix expression if operator is alphanumeric then print else: if it is ( : then push else if ): then pop till you get ( .and pop ( also else you get an operator: pop stack elements till the top has lower or equal priority than the current op (for left associativity ) [for right associativity pop only when the priority is greater] if stack is not empty ,pop elements and print them

Please check the main.cpp snippet for the solution.
