The bitwise AND operator (&) performs a logical AND operation on each corresponding bit of two integral operands. A bit in the result is set to 1 only if the corresponding bits in both operands are 1; otherwise, the result bit is 0.

Bitwise operators are commonly used in systems programming, embedded programming, device drivers, and applications that manipulate individual bits.

Source Code #

#include <iostream>

int main()
{
    int num1 = 12;
    int num2 = 10;

    int result = num1 & num2;

    std::cout << "First Number : " << num1 << '\n';
    std::cout << "Second Number: " << num2 << '\n';
    std::cout << "Result       : " << result << '\n';

    return 0;
}

Output #

First Number : 12
Second Number: 10
Result       : 8

Explanation #

• The bitwise AND operator (&) compares the corresponding bits of two integral operands.
• A result bit is set to 1 only when both corresponding operand bits are 1.
• If either corresponding bit is 0, the resulting bit is 0.
• The operands 12 and 10 have the following binary representations:12 = 1100₂ 10 = 1010₂ -------------- & = 1000₂
• The binary result 1000₂ is equal to the decimal value 8.
• Bitwise AND operations are commonly used for bit masking and testing specific bits.
• The bitwise AND operator is applicable only to integral data types.
• return 0; terminates the program successfully.
