Kotlin Program to Add Two Integers

In this program, you’ll learn to store and add two integer numbers in Kotlin. After addition, the final sum is displayed on the screen.

Example: Kotlin Program to Add Two Integers


fun main(args: Array<String>) {

    val first: Int = 10
    val second: Int = 20

    val sum = first + second

    println("The sum is: $sum")
}

When you run the program, the output will be:

The sum is: 30

In this program, similar to Java, two integers 10 and 20 are stored in integer variables first and second respectively. It is not mandatory to add :Int in the variable declaration, Kotlin automatically assigns a type (in this case Int).

Then, first and second are added using the + operator, and its result is stored in another variable sum.

Finally, sum is printed on the screen using println() function.

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
