Answer 1

I am writing a C++ program in which it will accept two integer values by the user and their values will be swapped without using any third variable. Kindly have a look over it.

#include<iostream.h>

#include<conio.h>

void main ()

{

clrscr() ;

int a, b ;

cout<<"Enter any two integer values of your choice \n";

cin>>a>>b;

{

a=a+b;

b=a-b;

a=a-b;

}

cout<<"After swapping the values are as under:- "<<endl;

cout<<" a = "<<a<<endl;

cout<<" b = "<<b<<endl;

getch();

}

Explanation by an example!

Suppose the values entered by the user are :-

a = 5

&

b = 7

So, according to the formula applied above:-

1) a = a + b

=> a = 5 + 7

a= 12

2) b = a - b

=> b = 12 - 7

b = 5

3) a = a - b

=> a = 12 - 5

a = 7

So, the program will swap the values in this way.

Answer 2

The code is written in python language

________CODE_________

a=int(input('please enter the first number:'))

b=int(input('please enter the second number:'))

a,b=b,a   #Swap

print('The new numbers are:',a,',',b,'respectively')

#PYTHON IS THE BEST
