Question

c. incrementally add and test small segments of code before integrating them
d. have only one developer test the game to maintain consistency

1. what is pseudocode primarily used for in programming?

a. to create working programs that can be executed by the computer
b. to plan and design algorithms before writing actual code
c. to document completed code for future reference
d. to encrypt sensitive parts of a program

1. how does iteration differ from sequencing in programming?

a. iteration involves making decisions, while sequencing does not
b. iteration requires more memory than sequencing
c. sequencing executes steps once in order, while iteration repeats a set of instructions
d. sequencing is only used in object - oriented programming, while iteration works in all paradigms

1. which statement about boolean conditions is correct?

a. boolean conditions can only be used in while loops
b. boolean conditions always evaluate to a number between 0 and 1
c. boolean conditions can only compare strings, not numbers
d. boolean conditions evaluate to either true or false

1. what is a key benefit of collaborative programming when debugging code?

a. it increases the complexity of the program
b. multiple perspectives can help identify and fix errors more efficiently
c. it eliminates the need for testing
d. it guarantees that no bugs will be present in the final program

1. in the context of creating computational artifacts, what does an \iterative and exploratory process\ refer to?

a. writing the entire program at once without planning

Explanation:

• Question 6: Pseudocode is a high - level description of an algorithm. It is not executable code (so A is wrong). It is mainly used for planning and designing algorithms before writing actual code (B is correct). It is not for documenting completed code (C is wrong) or encrypting (D is wrong).
• Question 7: Sequencing means executing steps in order one - time. Iteration is repeating a set of instructions. Making decisions is related to selection (not iteration vs sequencing, so A is wrong). Memory usage is not the key difference (B is wrong). Sequencing is not limited to object - oriented programming (D is wrong).
• Question 8: Boolean conditions can be used in various control structures like if - else statements, not just while loops (A is wrong). They evaluate to True or False (not a number between 0 and 1, B is wrong). They can compare numbers (e.g., x>5 where x is a number, C is wrong).
• Question 9: Collaborative programming does not increase program complexity (A is wrong). It does not eliminate the need for testing (C is wrong). It cannot guarantee no bugs (D is wrong). Multiple perspectives can help identify and fix errors more efficiently (B is correct).

Answer:

1. B. To plan and design algorithms before writing actual code
2. C. Sequencing executes steps once in order, while iteration repeats a set of instructions
3. D. Boolean conditions evaluate to either true or false
4. B. Multiple perspectives can help identify and fix errors more efficiently
