## Algorithm

1. Declare variables:
num1, num2, and temp are declared to store the two numbers and a temporary variable for swapping.

Input two numbers:
The user is prompted to input the values for num1 and num2.

Swap the numbers using a temporary variable:
The values of num1 and num2 are swapped using a temporary variable temp. This is a common technique to exchange values between two variables.

Display the swapped numbers:
The program prints the values of num1 and num2 after swapping to confirm the swap.

## Code Examples

### #1 Code Example-C++ Programing Swap Numbers (Using Temporary Variable)

```Code - C++ Programming```

``````#include <iostream>
using namespace std;

int main()
{
int a = 5, b = 10, temp;

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;

return 0;
}``````
Copy The Code &

Output

cmd
Before swapping.
a = 5, b = 10
After swapping.
a = 10, b = 5

### #2 Code Example- C++ Programing Swap Numbers Without Using Temporary Variables

```Code - C++ Programming```

``````#include <iostream>
using namespace std;

int main()
{

int a = 5, b = 10;

cout << "Before swapping." << endl;
cout << "a = " << a << ", b = " << b << endl;

a = a + b;
b = a - b;
a = a - b;

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

return 0;
}``````
Copy The Code &

Output

cmd
Before swapping.
a = 5, b = 10
After swapping.
a = 10, b = 5
