# Ruby program to demonstrate the bitwise left-shift (<<) operator

Ruby Example: Write a program to demonstrate the bitwise left-shift (<<) operator.
Submitted by Nidhi, on December 03, 2021

Problem Solution:

In this program, we are going to demonstrate the bitwise left-shift (<<) operator in the Ruby programming language.

Left shift (<<): The left shift operator (<<) shifts the first operand the specified number of bits to the left. Here, we will perform a bitwise left-shift (<<) operation between two variables and print the result.

Program/Source Code:

The source code to demonstrate the bitwise left-shift "<<" operator is given below. The given program is compiled and executed successfully.

```# Ruby program to demonstrate the
# bitwise left-shift "<<" operator

num1=4
num2=3
res =0

res = num1 << num2;

print num1," << ", num2," = ",res
```

Output:

```4 << 3 = 32
```

Explanation:

In the above program, we created three integer variables num1, num2, res that are initialized with 4, 3, 0 respectively. Then we performed a bitwise left shift operation using the "<<" operator and printed the result using the print() function.

Evolution of expression:

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