vc++中画线时xor

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

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

The xor_eq keyword performs EXCLUSIVE-OR operation and assigns the result to the left/first operand.

xor_eq关键字执行EXCLUSIVE-OR运算，并将结果分配给左/第一个操作数。

Syntax:

句法：

    operand_1 xor_eq 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 xor_eq mask;
Output:
value = 0110

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

// C++ example to demonstrate the use of
//'xor_eq' 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 xor_eq mask1;
cout << "After operation (1)...\n";
cout << "value: " << value << endl;
value xor_eq 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: 001
