Given two integer numbers first and second, we have to perform simple calculations like +, -, *, /, %.

Example:

    Input:
    first = 30
    second = 15
    choice = '+'

    Output:
    30 + 15 = 45

/**
 * Kotlin Program to Perform Simple Calculation on Two integer numbers
 * User have to  ( +, -, *, /, % ) put any choice to perform operation
 */

package com.includehelp.basic

import java.util.*


// Main Method Entry Point of Program
fun main(args: Array<String>) {
    // InputStream to get Input
    val reader = Scanner(System.`in`)

    //Input First Integer Value
    print("Enter Integer Value : ")
    var first = reader.nextInt()

    //Input Second Integer Value
    print("Enter Integer Value : ")
    var second = reader.nextInt()

    //Input Any Character as Choice
    print("Enter any Action( +, -, *, /, % ) :  ")
    val choice = reader.next()[0]

    try{
        var result = when(choice){
            '+' -> first+second
            '-' -> first-second
            '*' -> first*second
            '/' -> first/second
            '%' -> first%second
            else -> {
                System.err.println("Not a Valid Operation choice")
                return
            }
        }

        //Print Result
        println("Result is : $result")
    }catch (E:Exception){
        System.err.println("Exception  : ${E.toString()}")
    }
}

Output

RUN 1:
Enter Integer Value : 35
Enter Integer Value : 8
Enter any Action( +, -, *, /, % ) :  %
Result is : 3
---
RUN 2:
Enter Integer Value : 456
Enter Integer Value : 67
Enter any Action( +, -, *, /, % ) :  /
Result is : 6
