kotlin 兩個數字相加

Given two numbers, we have to swap them.

給定兩個數字，我們必須交換它們。

Example:

例：

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

要交換兩個數字 –在這里，我們使用第三個變量/臨時變量(考慮– 第一個包含第一個數字， 第二個包含第二個數字，而temp是一個臨時變量)。

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

  將第一個數字( first )分配給臨時變量( temp )

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

  現在，將第二個數字( second )分配給變量first 。

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

  現在，將溫度 (包含第一個數字)分配給第二個 。

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

  最后，交換值，然后將其打印在屏幕上。

計劃在Kotlin交換兩個數字 (Program to swap two numbers in Kotlin)

package com.includehelp.basicimport java.util.*// Main Method Entry Point of Program fun main(arg: Array<String>) {// InputStream to get Inputvar reader = Scanner(System.`in`)// Input two valuesprintln("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 Numbersvar temp = firstfirst=secondsecond=tempprintln("Numbers After Swap : \n first = $first \n second = $second ") }

Output

輸出量

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