# Kotlin: Unleashing the Power of Operators and Expressions

Just like any programming language, Kotlin has a rich set of operators to perform various operations such as arithmetic, assignment, comparison, and logic. By understanding these operators, you can unlock the potential of the Kotlin language and write more effective and efficient code.

## Basic Operators

Let’s begin with the basic operators:

### Arithmetic Operators

Arithmetic operators are used to perform mathematical operations like addition (+), subtraction (-), multiplication (*), and division (/).

``````fun main() {
val a = 10
val b = 20

println("a + b = \${a + b}") // output: a + b = 30
println("a - b = \${a - b}") // output: a - b = -10
println("a * b = \${a * b}") // output: a * b = 200
println("b / a = \${b / a}") // output: b / a = 2
}
``````

### Assignment Operators

Assignment operators are used to assign values to variables.

``````fun main() {
var a = 10
a += 20

println("a = \$a") // output: a = 30
}
``````

## Intermediate Operators

Next, we’re going to look at some intermediate operators.

### Comparison Operators

Comparison operators are used to compare two values.

``````fun main() {
val a = 10
val b = 20

println("a > b = \${a > b}") // output: a > b = false
println("a < b = \${a < b}") // output: a < b = true
}
``````

### Logical Operators

Logical operators are used to perform logic operations.

``````fun main() {
val a = true
val b = false

println("a && b = \${a && b}") // output: a && b = false
println("a || b = \${a || b}") // output: a || b = true
println("!a = \${!a}") // output: !a = false
}
``````

Finally, let’s delve into some advanced operators.

### Bitwise Operators

Bitwise operators are used to perform operations on bits.

``````fun main() {
val a = 3
val b = 2

println("a and b = \${a and b}") // output: a and b = 2
println("a or b = \${a or b}") // output: a or b = 3
}
``````

### In Operator

The ‘in’ operator is used to check if a value is present in a range, array or any other data structure.

``````fun main() {
val a = 3
val b = 1..5

println("a in b = \${a in b}") // output: a in b = true
}
``````

Understanding and mastering operators is a crucial step in becoming proficient in Kotlin. They help in controlling the flow of the program and manipulating data according to the requirements of the program. Always remember that practice is the key to proficiency in any programming language. Keep coding and exploring more with Kotlin. You are on your way to becoming a Kotlin Pro!
