# Kotlin program to check whether given number is positive, negative or zero

Kotlin | Checking number is positive, negative, or zero: Here, we are going to learn how to check whether a given number is positive, negative, or zero in Kotlin programming language?
Submitted by IncludeHelp, on April 24, 2020

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.

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

Example:

```    Input:
num = 12321

Output:
12321 is positive
```

### 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.basic

import java.util.*

//Main Function, Entry Point of Program
fun main(args: Array<String>) {
// InputStream to get Input

//Input Integer number
print("Enter Integer Number : ")

// 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")
else
println("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

```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
```
