# Assignment Operators and Augmented Assignment Operators in Kotlin

## Definition

- Assignment Operator is nothing but the "equal to - =" operator. This operator assigns a value to a variable.
- Augmented Assignment Operators performs operations and assigns the value to the same variable. There are 5 types of Augmented Assignment Operators. They are
- Addition and Assignment operator (+=)
- Subtraction and Assignment operator (-=)
- Multiplication and Assignment operator (*=)
- Division and Assignment operator (/=)
- Modulus and Assignment operator (%=)

## Syntax

### Assignment Operator

```
var variable_name1 = value
For example,
var number = 5
```

### Addition and Assignment Operator (Augmented Assignment operator)

```
var variable_name1 += value
For example,
var number += 5
```

### Subtraction and Assignment Operator (Augmented Assignment operator)

```
var variable_name1 -= value
For example,
var number -= 5
```

### Multiplication and Assignment Operator (Augmented Assignment operator)

```
var variable_name1 *= value
For example,
var number *= 5
```

### Division and Assignment Operator (Augmented Assignment operator)

```
var variable_name1 /= value
For example,
var number /= 5
```

### Modulus and Assignment Operator (Augmented Assignment operator)

```
var variable_name1 %= value
For example,
var number %= 5
```

## Assignment Operators and Augmented Assignment Operator Example Program in Kotlin

```
//Assignment Operators and Augmented Assignment Operators Example Program in Kotlin
//Operator Kotlin Programs, Basic Kotlin Program
fun main(args: Array<String>) {
val num1 = 100;
val num2 = 5
//Assigning num1 value to addition variable
var addition = num1
//Adding num2 to addition variable and assigning result to the addition variable
addition += num2
var subtraction = num1
//Subtracting num2 from subtraction variable and assigning result to the subtraction variable
subtraction -= num2
var multiplication = num1
//Multiplying num2 and multiplication variables and assigning result to the multiplication variable
multiplication *= num2
var division = num1
//Dividing division by num2 variable and assigning result to the division variable
division /= num2
//Modulus of modulus variable by num2 variable and assigning result to the modulus variable
var modulus = num1
modulus %= num2
println("addition and assignment of $num1 and $num2 is : $addition")
println("subtraction and assignment of $num1 and $num2 is : $subtraction")
println("multiplication and assignment of $num1 and $num2 is : $multiplication")
println("division and assignment of $num1 and $num2 is : $division")
println("modulus and assignment of $num1 and $num2 is : $modulus")
}
```

### Sample Output

```
addition and assignment of 100 and 5 is : 105
subtraction and assignment of 100 and 5 is : 95
multiplication and assignment of 100 and 5 is : 500
division and assignment of 100 and 5 is : 20
modulus and assignment of 100 and 5 is : 0
```
