kotlin 两个数字相加

Given two numbers, we have to swap them.

给定两个数字，我们必须交换它们。

Example:

例：

    Input:
First number: 10
Second number: 20
Output:
First number: 20
Second number: 10

To swap two numbers – here we are using third variable/temporary variable (consider – first contains the first number, second contains the second number and temp is a temporary variable).

要交换两个数字 –在这里，我们使用第三个变量/临时变量(考虑– 第一个包含第一个数字， 第二个包含第二个数字，而temp是一个临时变量)。

• Assign the first number (first) to the temporary variable (temp)

  将第一个数字( first )分配给临时变量( temp )

• Now, assign the second number (second) to the variable first.

  现在，将第二个数字( second )分配给变量first 。

• Now, assign the temp (that contains the first number) to the second.

  现在，将温度 (包含第一个数字)分配给第二个 。

• Finally, values are swapped, print them on the screen.

  最后，交换值，然后将其打印在屏幕上。

计划在Kotlin交换两个数字 (Program to swap two numbers in Kotlin)

package com.includehelp.basic
import java.util.*
// Main Method Entry Point of Program
fun main(arg: Array<String>) {
// InputStream to get Input
var reader = Scanner(System.`in`)
// Input two values
println("Enter First Value : ")
var first = reader.nextInt();
println("Enter Second Value : ")
var second = reader.nextInt();    
println("Numbers Before Swap : \n first = $first \n second = $second ")
//Code for Swap Numbers
var temp = first
first=second
second=temp
println("Numbers After  Swap : \n first = $first \n second = $second ")
}

Output

输出量

Run 1:
Enter First Value :
45
Enter Second Value :
12
Numbers Before Swap :
first = 45
second = 12
Numbers After  Swap :
first = 12
second = 45
