Program to swap and print two numbers.

Definition:-In computer programming, the act of swapping two variables refers to mutually exchanging the values of the variables. Usually, this is done with the data in memory. For example, in a program, two variables may be defined and using a memory place for three variables, and swapping one by one and finally reversing it.



Program:-

#include <iostream.h>
#include<conio.h>
void main()
{
    clrscr();
    int a, b, temp;
    cout<<"enter the first number to swap :- ";
    cin>>a;
    cout<<endl;
    cout<<"enter the second number to swap :- ";
    cin>>b;
    cout<<endl;
    cout<<"\n";
    cout << "Before swapping." << endl;
    cout << "a = " << a << ", b = " << b << endl;

    temp = a;
    a = b;
    b = temp;

    cout << "\nAfter swapping." << endl;
    cout << "a = " << a << ", b = " << b << endl;

getch();
}

Output:-
