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 usingastack? I am using avectorvector<char>as a stack here. The following is my code: #include<iostream>...

总体思路是这种：遇到数字的话直接输出，遇到右括号 输出左括号上面的所有元素 ，遇到左括号入栈。
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 ...
Convert Infix to Postfix Notation Initially we’ve astringS which represent the expression in infix format. Now we need a characterstack. *We’ll iterate through thestringS, from left to right. Whenever we encounter an operand we’ll print it. ...
