Infix to Postfix Conversion using Stack in C Conversion of Infix to Postfix can be done using stack. The stack is used to reverse the order of operators. Stack stores the operator because it can not be added to the postfix expression until both of its operands are added. The precedence of...

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. ...

1. Conversion from Infix to Postfix Notation Supported Mathematical Operators: +, - (unary and binary) *, /, ^ Supported Functions: sin, cos, tan, cot, sqrt, ln, exp Supported Constants PI Description: The expression is converted using a stack for operators. 2. Evaluation of Postfix Ex...
