kotlin hello world
Here is a Kotlin code snippet for a simple "Hello, World!" program, along with explanations for each step:
fun main() {
println("Hello, World!")
}
Step 1: Function Declaration
The keyword fun
is used to declare a function in Kotlin. In this case, we are declaring a function named main
, which is the entry point of the program.
Step 2: Function Body
The code block enclosed within curly braces {}
represents the body of the main
function. This is where the actual code of the function resides.
Step 3: Print Statement
The println()
function is used to print a line of text to the console. In this case, we are printing the string "Hello, World!"
.
Step 4: Execution
When the program is run, the main
function is executed. The println()
function is called, which prints the specified text to the console.
That's it! This code will output "Hello, World!" when executed.
