Example : *+AB-CD (Infix : (A+B) * (C-D) ) Postfix: An expression is called the postfix expression if the operator appears in the expression after the operands. Simply of the form (operand1 operand2 operator). Example : AB+CD-* (Infix : (A+B * (C-D) ) Given a Prefix expr...
Example 1: Input: a * ( b + c + d) Output: abc+d+* Example 2: Input: a*b Output: ab* Before discussing the solution of infix to postfix conversion using stack in C, let us first learn about the Arithmetic Notations. What are Arithmetic Notations Any arithmetic expression consists of...

1、操作符栈压入"#"; 2、依次读入表达式的每个单词; 3、如果是操作数则压入操作数栈; 4、如果是操作符,则将操作符栈顶元素与要读入的操作符进行优先级比较 (4.1)如果读入的是 ')',则将操作符栈中的元素压入操作数栈直至遇到 '('; (4.2)如果读入的是 '(',压入操作符栈; (4.3)如果栈顶元素优先级...
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. ...
The computer cannot differentiate the operators and parenthesis easily, that's why postfix conversion is needed. To convert infix expression to postfix expression, we will use the stack data structure. By scanning the infix expression from left to right, when we will get any operand, simply add...
