Golang program to demonstrate the bitwise Left Shift (<<) operator

Here, we are going to demonstrate the bitwise Left Shift (<<) operator in Golang (Go Language). By Nidhi Last updated : March 28, 2023

Bitwise Left Shift (<<) Operator Example in Golang

In this program, we will read an integer number and perform the bitwise left-shift operation and print the result on the console screen.

Golang code to demonstrate the example of Bitwise Left Shift (<<) Operator

The source code to demonstrate the bitwise Left Shift (<<) operator is given below. The given program is compiled and executed successfully.

// Golang program to demonstrate the 
// Left Shift (<<) operator.

package main
import "fmt"

func main() {
    var num int=0
    var res int=0

    fmt.Printf("Enter number: ")
    fmt.Scanf("%d",&num)
    
    res = num << 3
    fmt.Printf("Result: %d",res)
}

Output

Enter number: 4
Result: 32

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 two variables num and res that are initialized with 0. Then we read the value of the variable num from the user. Then we performed a bitwise left shift operation.

Here, we entered the value 4 for integer variable num, now we will evaluate the below expression,

res = num << 3
res = 4 * (23)
res = 4 * 8
res = 32

After that we printed the value of variable res on the console screen.
