| 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

cs 复制代码

#include <stdbool.h>

bool xor(bool a, bool b) {
  if(a==b)
     
    return false;
  else
    return true;
}
