Golang program to demonstrate the BITWISE AND (&) operator

Here, we are going to demonstrate the BITWISE AND (&) operator in Golang (Go Language).
Submitted by Nidhi, on February 17, 2021

Problem Solution:

In this program, we will read two integer numbers and perform a BITWISE AND (&) operation and print the result on the console screen.

Program/Source Code:

The source code to demonstrate the BITWISE AND (&) operator is given below. The given program is compiled and executed successfully.

// Golang program to demonstrate the 
// BITWISE AND (&) operator.

package main
import "fmt"

func main() {
    var num1 int=0
    var num2 int=0
    var res int=0
    
    fmt.Printf("Enter number1: ")
    fmt.Scanf("%d",&num1)
    
    fmt.Printf("Enter number2: ")
    fmt.Scanf("%d",&num2)
    
    res = num1 & num2
    fmt.Printf("Result: %d",res)
}

Output:

Enter number1: 3
Enter number2: 2
Result: 2

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

Here, we created the main() function. The main() function is the entry point for the program. In the main() function, we created three variables num1, num2, and res that are initialized with 0. Then we read the values of variables num1 and num2 from the user.  Here, we performed bitwise AND operation.

Now evaluate the above expression,

res = num1 & num2
res = 3 & 2

The binary equivalent of 3 is 11.
The binary equivalent of 2 is 10.

Then

11
10
====
10

That is 2.

At last, we printed the value of variable res on the console screen.
