kotlin read input as int

To read input as an integer in Kotlin, you can make use of the readLine() function and the toInt() method. Here are the steps involved:

1. Use the readLine() function to read the input as a string. This function reads a line of text from the standard input (usually the console) and returns it as a string.

2. Assign the input to a variable of type String to store the user's input.

3. Use the toInt() method to convert the input string to an integer. This method is called on the input string variable and returns the integer representation of the string.

4. Assign the converted value to a variable of type Int to store the integer value.

Here's an example of how you can implement these steps:

fun main() {
    print("Enter an integer: ")
    val inputString: String? = readLine()
    val intValue: Int? = inputString?.toInt()

    if (intValue != null) {
        println("You entered: $intValue")
    } else {
        println("Invalid input")
    }
}

In this example, we prompt the user to enter an integer, read the input as a string using readLine(), convert it to an integer using toInt(), and then print the entered value or display an error message if the input is invalid.

I hope this explanation helps you understand how to read input as an integer in Kotlin.
