Computing Gr 7 Sem Exam 1 Review

What is a key characteristic of pseudocode?

• It must be lengthy and complex.

• It should be short, clear, and precise.

• It can be written in any programming language.

• It does not need to indicate the start and end.

Why is it important to understand pseudocode?

• It is the only way to write algorithms.

• It helps in following and understanding algorithms easily.

• Pseudocode is more accurate than programming languages.

• It eliminates the need for testing algorithms.

Which of the following can flowcharts represent?

• Only linear algorithms

• Algorithms with conditional statements

• Algorithms without any conditions

• Only pseudocode

What is necessary to effectively predict the outcome of an algorithm?

• Guessing based on previous knowledge

• Testing the algorithm

• Writing it in pseudocode

• Reading it without execution

What does decomposing a problem involve?

• Ignoring complex parts

• Breaking it down into sub-problems

• Solving the entire problem at once

• Rewriting the problem in pseudocode

Which statement is true regarding constants in algorithms?

• Algorithms must always use at least one constant.

• Constants are optional in algorithms.

• Constants can only be used in flowcharts.

• Algorithms cannot function without constants.

Why are searching algorithms necessary?

• To speed up the process of finding specific data.

• To eliminate the need for data organization.

• They are not necessary in modern computing.

• To reduce the number of programming languages.

What does a linear search do?

• It finds the desired item by dividing the list.

• It examines each element in a list one by one.

• It can only search sorted lists.

• It uses complex algorithms to find items.

Which of the following statements is false?

• Linear search is one way to search for an item.

• There are multiple searching methods available.

• Linear search is the only method for searching.

• Searching algorithms help locate specific data.

In what context can pseudocode be especially useful?

• Communicating algorithms to both technical and non-technical audiences.

• Only in programming competitions.

• When writing complex code in a specific language.

• To replace all programming languages.
