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...
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 ...
6. Repeat steps 2-6 until infix expression is scanned. 7. Append the remaing items int the stack. publicclassInfoxToPostfix {privateintorder(charch) {switch(ch) {case'+':case'-':return1;case'*':case'/':return2;case'^':return3;default:return-1; } }privateString infixToPostfix(Strin...
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. The following is my code: #include<iostream>#include<...

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 E...
6. Conversion of Infix to Postfix One of the applications of postfix notation is to build a calculator or evaluate expressions in a programming language. In addition, we can evaluate postfix expressions efficiently using a stack data structure. ...
