You will need to update your algorithm on lines 29–32 to get all the digits of a number and store them in a single string, then add that to your postfix vector. A really easy way to deal with all this is to require your input to have spaces between tokens, and use>>to get each...
The following are the steps (algorithm) to convert an infix expression to a postfix expression: Let,Xis an arithmetic expression written in infix notation. Push "("onto Stack, and add ")" to the end of X. Scan X from left to right and repeat Step 3 to 6 for each element of X unt...
Ques 2. How do we convert infix to postfix using stack? Ans. The algorithm for converting infix to postfix notation involves using a stack to keep track of operators and their precedence. We scan the infix expression from left to right, and for each symbol we encounter, we take different ...
The evaluation process must be efficient and handle any valid postfix expression. ### Algorithm Review 1. Initialize an empty stack. 2. Scan the postfix expression from left to right: If the symbol is an operand, push it onto the stack. If the symbol is an operator: Pop the top two op...

The three most important orderings are called preorder, in order and post order. These all ordering having a specific algorithm, & this algorithm is complicated for keep in mind for student side ,so this paper gives solution to find systematic order of node using graphical notation, this is ...
Algorithm infixToPostfix(infix) Input − Infix expression. Output − Convert infix expression to postfix form. Begin initially push some special character say # into the stack for each character ch from infix expression, do if ch is alphanumeric character, then add ch to postfix expression ...
Sep 20, 2008 at 10:59pm komal(13) I need to write a program that reads a file as input and converts prefix to postfix and infix.. I wanted to know if I should do this using trees or think of an algorithm to convert it .. ...
Algorithm First, we have to fix the precedence of the expression. To convert the infix expression to its postfix expression, we have to take care of the following conditions: If the characters are in between 0-9 or a-z or A-Z, then we insert them to another array. If there is “...
