Exclusive "or" (xor) Logical Operator

Overview

In some scripting languages like PHP, there exists a logical operator (e.g. &&, ||, and, or, etc.) called the "Exclusive Or" (hence the name of this Kata). The exclusive or evaluates two booleans. It then returns true if exactly one of the two expressions are true, false otherwise. For example:

测试用例

false xor false == false // since both are false
true xor false == true // exactly one of the two expressions are true
false xor true == true // exactly one of the two expressions are true
true xor true == false // Both are true. "xor" only returns true if EXACTLY one of the two expressions evaluate to true.

二、解题

1、分析

两者相同返回false，两者不同返回true。

2、思路

（1）a==b return false;

（2）a!=b return true;

三、Myway

#include <stdbool.h>bool xor(bool a, bool b) {if(a==b)return false;elsereturn true;
}
