Step 1: Reverse the infix expression i. Repeat this step as long as stack is not empty and topStack has precedence over the character. We will understand the Rules to convert an infix expression to postfix and also understand the pseudocode. I've done the entire program but the output is displaying in reverse i. By using a stack algorithm Initialize an empty stack Repeat the following until the end of the expression is encountered Get the next token (const, var, operator) in the expression Operand –push onto stack Operator –do the following Pop 2 values from stack Apply operator to the two values Push resulting value back onto stack. Input Postfix expression must be in a desired format. Infix notation: X + Y Operators are written in-between their operands. Push “)” onto STACK, and add “(“ to end of the A Step 2. It will take only single digit in. in this program you need to extends Stack;better you create stack general type class and extends that one to this program. Reverse polish notation (otherwise known as post-fix, RPN for short) is a way of representing mathematical expressions. Write a C++ program to create a class called EXPRESSION. (b) If precedence of scanned operator is greater then the precedence of topmost operator in the stack then PUSH scanned operator into stack.

Array based Linked list based Stacks Stacks. Infix to postfix conversion. Steps to convert infix to prefix expression: Scan the valid infix expression from right to left. If the character is an operator, and the operator stack is empty then push it onto the operator stack. The notation is used because the format that the expression is in is easier for machines to interpret rather than the notation we are used to, infix notation, where the operator is in between the numbers. In this section, we consider three such data types, known as the bag, the queue, and the stack. The only difference in converting Infix to Prefix from converting Infix to Postfix is that we should reverse the input string and use the same logic and again reverse the output.
