C++ 'bitor' Keyword with Example

C++ | 'bitor' keyword: Here, we are going to learn about the 'bitor' keyword which is an alternative to Bitwise OR operator.
Submitted by IncludeHelp, on May 16, 2020

"bitor" is an inbuilt keyword that has been around since at least C++98. It is an alternative to | (Bitwise OR) operator and it mostly uses for bit manipulations.

The bitor keyword compares two bits and returns 1 if either of the bits is 1 and it returns 0 if both bits are 0 or 1.

Syntax:

    operand_1 bitor operand_2;

Here, operand_1 and operand_2 are the operands.

Example:

    Input:
    bitset<4> value("1100");
    bitset<4> mask ("1010");
        
    value = value bitor mask;

    Output:
    value = 1110

C++ example to demonstrate the use of "bitor" keyword

// C++ example to demonstrate the use of
// 'bitor' 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 bitor mask1;

    cout << "After operation (1)...\n";
    cout << "value: " << value << endl;

    value = value bitor mask2;

    cout << "After operation (2)...\n";
    cout << "value: " << value << endl;

    return 0;
}

Output:

value: 1011
mask1: 1100
mask2: 0100
After operation (1)...
value: 1111
After operation (2)...
value: 1111
