We have given an Arithmetic Expression and we have to write a program that converts the infix to postfix using stack in C. The Expression will be given in the form of a string, where alphabetic characters i.e a-z or A-Z denotes operands and operators are ( +, –, *, / ). Expres...

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. ...

Postfix: AB+CD-* 算法: 1. Scan the infix expression from left to right. 2. If the scanned character is an operand, append it to result. 3. Else 3.1 If the precedence of the scanned operator is greater than the precedence of the operator in the stack(or the stack is empty or the ...
