# C# program to demonstrate the example of the left-shift operator

Left-shift operator in C#: Here, we are going to learn about the left-shift operator and how it works with C# program?
Submitted by Nidhi, on August 18, 2020

Here we will create a program to demonstrate the left shift operation with different values.

Program:

The source code to demonstrate the left shift operations with different values in C# is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

```//Program to demonstrate the
//example of the left-shift operator in C#.

using System;

class LeftShiftDemo
{
public static void Main()
{
int X = 128;
int Y = 256;

int R = 0;

R = X << 2;
Console.WriteLine("X<<2 = " + R);

R = Y << 3;
Console.WriteLine("Y<<3 = " + R);
}
}
```

Output:

```X<<2 = 512
Y<<3 = 2048
Press any key to continue . . .
```

Explanation:

In the above program, we created a LeftShiftDemo class that contains the Main() method, here we created three integer variables X, Y, and R initialized with 128, 256, and 0.

Now calculate the statements.

```R = X << 2;
R  =  128 * Power(2,2);
R  =  128 * 2*2;
R  =  256;
```

Then,

```R = Y << 3;
R = 256 << 3;
R = 256* Power(2,3);
R = 256*(2*2*2);
R = 2048;
```
