Writing an Algorithm: Your next step will be to write an algorithm that includes the three control structures (sequence, selection, and repetition). First, explain the purpose of the algorithm by providing a brief description for the task being performed. Then, list the details of the algorithm. Remember to include all three control structures (sequence, selection, and repetition).

Select ONE of the following tasks as the basis for completing your algorithm:

  • Changing a television channel by using a remote control
  • Using a sponge to wash a car
  • Walking up a set of stairs

Paper For Above Instructions

The goal of this assignment is to modify existing algorithms to improve their functionality by ensuring they correctly implement the required tasks and control structures. The first algorithm focuses on calculating sales bonuses for ten salespersons based on their sales amounts. The second involves ensuring accuracy in a navigation algorithm with repetition and condition checking.

Improved Algorithm to Print Sales Amounts

The modified algorithm below will iterate through a list of ten salespersons, retrieve their names and sales amounts, calculate the bonuses, and print the results.

1. Initialize an array of salespersons' names


2. Initialize an array of sales amounts


3. Set the number of salespersons to 10


4. For i from 0 to 9:


a. Get the salesperson's name


b. Get the sales amount


c. Calculate the bonus as sales amount * 0.03


d. Print "Salesperson Name: " + name + ", Bonus Amount: " + bonus


5. End For

The algorithm emphasizes the use of repetition through the 'For' loop, ensuring that all salespersons' data is processed adequately. This is crucial for accurate results and efficient code.

Fixing the Navigation Algorithm

The navigation task requires a revision to include the repetition structure while ensuring accurate execution by checking for the presence of flowers before deciding to pick them.

1. Repeat until the path is clear:


a. Walk forward 1 step


b. Walk forward 1 step


c. If a flower is present, then:


i. Pick up the flower


d. Turn left 45 degrees


e. Turn left 45 degrees


End Repeat

Here, the repetition is established through the 'Repeat until' structure, allowing continuous movement until there are no obstruction or flowers. The corrections made help maintain clarity and flow.

Writing a New Algorithm

For this part, we will write an algorithm for changing a television channel using a remote control, which incorporates sequence, selection, and repetition control structures.

1. Start


2. Initialize the current channel to 1


3. While true:


a. Print "Current channel is: " + current channel


b. Print "Press 1 to change channel up"


c. Print "Press 2 to change channel down"


d. Print "Press 3 to exit"


e. Get user input


f. If input is 1 then:


i. Increase current channel by 1


g. Else if input is 2 then:


i. Decrease current channel by 1


h. Else if input is 3 then:


i. Exit


i. End If


End While


3. End

The algorithm follows a sequence of displaying the current channel and providing choices to the user. Selection is used to navigate based on user input, while repetition allows the user to continue changing channels until they decide to exit.

Conclusion

In summary, modifying algorithms to ensure accuracy and the inclusion of necessary control structures is vital for their effectiveness. By refining the sales calculation algorithm and ensuring the robustness of the navigation and channel-changing algorithms, we uphold the principles of good algorithm design.
