Explanation:
1. fun main() { ... }
: Defines the main function where the program execution begins.
2. val result = calculateResult()
: Declares a variable result
and assigns the value returned by the calculateResult()
function.
3. fun calculateResult(): Int { ... }
: Defines a function calculateResult()
that returns an integer. It calculates the result by adding two numbers and returns the sum.
4. val num1 = 10
and val num2 = 5
: Declares two variables num1
and num2
with integer values 10 and 5, respectively, within the calculateResult()
function.
5. return addNumbers(num1, num2)
: Calls the addNumbers()
function with num1
and num2
as arguments and returns the result obtained from this function.
6. fun addNumbers(a: Int, b: Int): Int { ... }
: Defines the addNumbers()
function that takes two integer arguments a
and b
and returns their sum as an integer value.
7. return a + b
: Adds the values of a
and b
and returns the sum as the result of the function.
