The precedence of the operator also matters while converting infix to postfix using stack, which we will discuss in the algorithm. Note: Parentheses are used to override the precedence of operators, and they can be nested parentheses that need to be evaluated from inner to outer. Algorithm for...

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 usingastack? I am using avectorvector<char>as a stack here. ...

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*...
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 ...
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...
