fun is a leyword used to define a function.

1 fun main() {
2     println("Happy Birthday!")
3     println("Jhansi")
4     println("You are 25!")
5 }

print() vs println()

• print() just prints the text without using a line break at end of string.

val keyword is used to store the values that can be set only once. same like const in js. For declaring a changeable variable use var

1    val age = 15

To use a variable inside a print statement surround it with {}

1   println("Age of a Surya is ${age}")

Use a repeat() function to repeat an instruction for ‘n’ number of times. This is one of a kind of loops

1    printSigns(){
2        //prints + sign for 50 times
3        repeat(50){
4            print("+")
5        }
6    }

• To create a Nested loop use repeat() inside a repeat()

  1//print the layers of the cake age times
  2fun printCakeBottom(age: Int, layers: Int) {
  3   repeat(layers) {
  4      repeat(age + 2) {
  5       print("@")
  6      }
  7      println()
  8   }
  9}
