C++ Program to swap two numbers using the third variable.

Let see the program swap two numbers using the third variable.

Example:

Declare three variables they are 
integer or float data types x, y, z.

x=10
y=20

Swap two numbers.

 z=x;
X value store in z

x=y;

y value store in x

y=z

z value store in y

After swapping of two numbers

x=20

y=10

#include <iostream>

using namespace std;
int main()
{
    int x,y,z;
    cout<<"Enter x value :";
    cin>>x;
    cout<<"Enter y value :";
    cin>>y;
    cout<<" Before swapping x value :"<<x<<endl;
     cout<<" Before swapping y value :"<<y<<endl;
    z=x;
    x=y;
    y=z;
    cout<<" After swapping x value :"<<x<<endl;
    cout<<" After swapping y value :"<<y<<endl;
    return 0;
}

Output:

 Enter x value :10
 Enter y value :20
 Before swapping x value :10
 Before swapping y value :20
 After swapping x value :20
 After swapping y value:10
