kotlin 判斷數字

A positive number is a number which is greater than 0, a negative number is a number which is less than 0, else the number is Zero.

正數是大于0的數字，負數是小于0的數字，否則為零。

Given a number num, we have to check whether it is positive, negative, or zero.

給定數字num ，我們必須檢查它是正數，負數還是零。

Example:

例：

Input:num = 12321Output:12321 is positive

在Kotlin中檢查數字為正，負或零的程序 (Program to check number is positive, negative or zero in Kotlin)

/* Kotlin Program to Check a Integer Number is Positive or Negative or Zero if number > 0 = Positive Number else if number < 0 = Negative Number else Number is 0 (Zero) */package com.includehelp.basicimport java.util.*//Main Function, Entry Point of Program fun main(args: Array<String>) {// InputStream to get Inputval reader = Scanner(System.`in`)//Input Integer numberprint("Enter Integer Number : ")val num = reader.nextInt()// using if else println("Using if else...")if (num > 0)println("$num is a Positive Number")else if (num < 0)println("$num is a Negative Number")elseprintln("Entered Number is Zero")// using when statement (similar to switch case)println("Using when statement...") when{num> 0 -> println("$num is a Positive Number")num< 0 -> println("$num is a Negative Number")else -> println("Entered Number is Zero")} }

Output

輸出量

Run 1: Enter Integer Number : -10 Using if else... -10 is a Negative Number Using when statement... -10 is a Negative Number----Run 2: Enter Integer Number : 10 Using if else... 10 is a Positive Number Using when statement... 10 is a Positive Number---- Run 2: Enter Integer Number : 0 Using if else... Entered Number is Zero Using when statement... Entered Number is Zero
