Algorithm for Conversion of Infix to Postfix using Stack in C Here are the steps of the algorithm to convert Infix to postfix using stack in C: Scan all the symbols one by one from left to right in the given Infix Expression. If the reading symbol is an operand, then immediately append...

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. ...

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 else ...
Popping Remaining Operators from the Stack: After traversing the entire string, remaining operators are popped from the stack and added to the postfix string. Example Usage of the infix_to_postfix Function Let's consider the algorithm's operation using the expression -2*ln(x)/(4*-2*sin(5*...
The following algorithm will output a string in postfix order. We process the infix expression from left to right. For each token, four cases can arise: If the current token is an opening bracket,'(', push it into the stack. If the current token is a closing bracket,')', pop tokens...
