Question

how to write pseudocode swap the content of two variables using athird variable

Answer 1

1. Start

2. Declare and initialize two variables, let's say A and B
3. Declare an empty variable, let's say C
4. Copy the value of A into C
5. Copy the value of B into A
6. Copy the value of C into B
7. End

Answer 2

To swap the content of two variables using a third variable in pseudocode, follow these steps:

1. Start by declaring the variables and assigning them values.
2. Create a temporary variable to store the value of one of the variables.
3. Assign the value of the first variable to the temporary variable.
4. Assign the value of the second variable to the first variable.
5. Finally, assign the value of the temporary variable to the second variable.

Here is the pseudocode example:

```
// Step 1: Declare and initialize the two variables
DECLARE firstVariable, secondVariable, tempVariable

SET firstVariable = 5
SET secondVariable = 10

// Step 2: Swap the values using a temporary variable
SET tempVariable = firstVariable
SET firstVariable = secondVariable
SET secondVariable = tempVariable
```

After executing this pseudocode, the values of `firstVariable` and `secondVariable` will be swapped. `firstVariable` will contain the value `10`, and `secondVariable` will contain the value `5`.
