kotlin 計算平方

Given a number number, and we have to calculate the sum of all natural numbers from 1 to number.

鑒于一些數字 ，我們必須從1計算所有自然數的總和數量 。

Example:

例：

    Input:
number = 15
Output:
120

用于計算Kotlin中自然數之和的程序 (Program to calculate the sum of natural numbers in Kotlin)

package com.includehelp.basic
import java.util.*
//Main Function entry Point of Program
fun main(args: Array<String>) {
//Input Stream
val scanner = Scanner(System.`in`)
//input integer number
print("Enter Number  : ")
val number: Int = scanner.nextInt()
var sum=0
//Iterate through loop to calculate sum
for(i in 1..number){
sum+=i
}
//Print Sum
println("Sum of All Natural Numbers up to $number are : $sum")
}

Output

輸出量

Run 1:
Enter Number  : 15
Sum of All Natural Numbers up to 15 are : 120
---
Run 2:
Enter Number  : 99
Sum of All Natural Numbers up to 99 are : 4950
---
Run 3:
Enter Number  : 456
Sum of All Natural Numbers up to 456 are : 104196
