Kotlin Program to Add two Numbers

In this article, we will understand how to add two numbers. This can be done using the ?+? operator. Below is a demonstration of the same

Suppose our input is

input1 : 10
input2 : 15

The desired output would be

Sum : 25

Algorithm

• Step 1 ? Start

• Step 2 ? Declare three integers: val1, val2 and sum

• Step 3 ? Define the integers

• Step 4 ? Add the two values using an addition operator (+)

• Step 5 ? Display the result

• Step 6 ? Stop

Example 1

In this example, we will add two numbers using the + operator. First, declare and set two integers i.e. number ?

val val1 = 10
val val2 = 15

Now, calculate the sum using the Addition Arithmetic Operator ?

val sum = val1 + val2

Let us now see the complete example ?

fun main() {
   val val1 = 10
   val val2 = 15
   println("The two numbers are defined as " +val1 +" and " +val2)
   val sum = val1 + val2
   println("The sum of the two integers is: " +sum)
}

Output

The two numbers are defined as 10 and 15
The sum of the two integers is: 25

Example 2

Here, we have created a custom function

fun sum(val1 : Int, val2 : Int){
   val sum = val1 + val2
   println("The sum of the two integers is: " +sum)
}
fun main() {
   val val1 = 10
   val val2 = 15
   println("The two numbers are defined as " +val1 +" and " +val2)
   sum(val1, val2)
}

Output

The two numbers are defined as 10 and 15
The sum of the two integers is: 25
