Question

Write a program to swap values of two variables using third variable.​

Answer 1

Answer:

I am doing the program in Java. The solution is simple as follows:

import java.util.Scanner;//Using only the scanner class of util package

public class Swapping

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);//creating object(sc) of Scanner class

int a,b,c=0;//Declaring the variables

System.out.println("Enter the first number:");

a=sc.nextInt();//Input of the first number

b=sc.nextInt();//Input of the second number

c=b;//storing the value of variable b in variable c

b=a;//storing the value of variable a in variable b

a=c;//storing the value of variable c in variable a(it actually has the value of variable b)

System.out.println("After swapping the first number becomes:"+a);

system.out.println("After swapping the second number becomes:"+b);

}

}

Try this out. I hope that no problem will occur but if any problem occurs then let me know. Happy to help you :)
