Answer 2

Hey friend, Harish here.

Here is your answer.

1st program.

#include<iostream.h>

#include<conio.h>

void main()

{

int a,b,c;

clrscr();

cout<<"Enter value of a: ";

cin>>a;

cout<<"Enter value of b: ";

cin>>b;

c=a;

a=b;

b=c;

cout<<"After swap a: "<<a<<"b: "<<b;

getch();

}

2nd method:

#include<iostream.h>

#include<conio.h>

void main()

{

int a,b;

clrscr();

cout<<"Enter value of a: ";

cin>>a;

cout<<"Enter value of b: ";

cin>>b;

a=a+b;

b=a-b;

a=a-b;

cout<<"After swap a: "<<a<<"b: "<<b;

getch();

}

3rd method:

#include<iostream>

using name_space std;

{

b = a + b;

a = b - a;

b = b - a;

}

int main()

{

int a, b;

cout << "Enter two numbers to be swapped : ";

cin >> a >> b;

swap(a, b);

cout << "The two numbers after swapping become :" << endl;

cout << "Value of a : " << a << endl;

cout << "Value of b : " << b << endl;

}

These are programs using Temporary variable and without temporary variable.
