Input

You can take values as input from the user using the readLine() function.

For example, we can ask the user to enter their age and store it in a variable:


==============================

readLine() returns the input as a string, even if the user enters a number.

So how do we take numbers as input?

We need to convert the input to the corresponding type. For example, to convert to Int we need to use toInt():


The code above takes two integers as input and outputs their sum.
