compl c++_C ++’compl’关键字和示例

compl c++

“compl” is an inbuilt keyword that has been around since at least C++98. It is an alternative to ~ (Compliment) operator and it mostly uses for bit manipulations.

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

The compl keyword inverts all of the bits of the operand.

compl关键字将操作数的所有位取反。

Syntax:

句法：

 compl operand  

Here, operand is the operand.

在此， 操作数是操作数。

Example:

例：

 Input: bitset<4> value("1100"); value = compl value; Output: value = 0011  

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

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

Output:

输出：

value: 1011 After operation (1)... value: 0100 After operation (2)... value: 1011
