vc++中画线时xor

**"xor"** is an inbuilt keyword that has been around since at least C++98. It is an alternative to ^ (**EXCLUSIVE-OR**) operator and it mostly uses for bit manipulations.

**“ xor”**是一个内置关键字，至少从C ++ 98起就存在。 它是^ ( **EXCLUSIVE-OR** )运算符的替代方法，它主要用于位操作。

The **xor keyword** compares two bits and returns 1 if the bits are complementary; otherwise, it returns 0.

**xor关键字**比较两个位，如果两个位互补，则返回1；否则，返回1。 否则，返回0。

**Syntax:**

**句法：**

operand_1 xor operand_2;

Here, operand\_1 and operand\_2 are the operands.

在这里，操作数\_1和操作数\_2是操作数。

**Example:**

**例：**

Input:
        bitset<4> value("1100");
        bitset<4> mask ("1010");
            
        value = value xor mask;
    
        Output:
        value = 0110

## 演示使用“ xor”关键字的C ++示例 **(**C++ example to demonstrate the use of "xor" keyword**)** ##

// C++ example to demonstrate the use of
    // 'xor' keyword
    
    #include <iostream>
    #include <bitset>
    using namespace std;
    
    int main()
    {
        
        //bitsets
        bitset<4> value("1011");
        bitset<4> mask1("1100");
        bitset<4> mask2("0100");
    
        // before operation
        cout << "value: " << value << endl;
        cout << "mask1: " << mask1 << endl;
        cout << "mask2: " << mask2 << endl;
    
        value = value xor mask1;
    
        cout << "After operation (1)...\n";
        cout << "value: " << value << endl;
    
        value = value xor mask2;
    
        cout << "After operation (2)...\n";
        cout << "value: " << value << endl;
    
        return 0;
    }

**Output:**

**输出：**

value: 1011
    mask1: 1100
    mask2: 0100
    After operation (1)...
    value: 0111
    After operation (2)...
    value: 0011
