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...
广义上infix是给user看的,prefix和postfix很大程度上是给编译器看的。具体地,对于单操作符运算,其实用的是prefix(比如取非),当然常见的prefix/postfix就是++、--,但是python中没有这个操作符。 有用 回复 DumplingsYang: 了解了,多谢啦 回复2017-10-10 撰写回答 你尚未登录,登录后可以 和开发者交流问题的细...

While we use infix expressions in our day to day lives. Computers have trouble understanding this format because they need to keep in mind rules of operator precedence and also brackets. Prefix and Postfix expressions are easier for a computer to understand and evaluate. Given two operands a and...
