c++ swapping two numbers

To swap two numbers in C++, you can use a temporary variable to store the value of one of the numbers before exchanging them. Here are the steps to swap two numbers in C++:

1. Declare and initialize two variables, let's say a and b, with the values you want to swap.

2. Declare a temporary variable, let's say temp, to store the value of a temporarily.

3. Assign the value of b to a. This step replaces the value of a with the value of b.

4. Assign the value of temp to b. This step replaces the value of b with the original value of a that was stored in temp.

After these steps, the values of a and b will be swapped.

Here is the code snippet that demonstrates the swapping of two numbers in C++:

int main() {
    int a = 10;
    int b = 20;
    int temp;

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

    return 0;
}

In this example, we have two numbers, a with a value of 10 and b with a value of 20. By using a temporary variable temp, the values of a and b are swapped, resulting in a being 20 and b being 10.
