Thinking Logically and Concurrently

What is the primary purpose of thinking logically about conditions and decisions in programming?

• To increase program speed
• To determine the outcome of a decision
• To reduce the number of loops
• To optimise memory usage

How should you check if decisions and conditions have been set correctly in an algorithm?

• Run the program and see if it works
• Hand-trace the algorithm using a trace table
• Use a debugger tool
• Ask a colleague for feedback

What is the purpose of a trace table in programming?

• To write pseudocode
• To identify variables in the program
• To debug code
• To track variable values as the program executes

When completing a trace table, what should you include?

• Variables

• Iteration conditions

• Outputs

• Selection conditions

What is the purpose of a validation routine in programming?

• To make the program run faster
• To check if the computer is working correctly
• To check user input for processing

• To generate random numbers

What can human error potentially cause in validation routines?

• Improved accuracy
• Faster execution
• Problems with the final solution
• Smoother user experience

What is concurrent processing in the context of programming?

• Running multiple programs simultaneously
• Processing data concurrently
• Switching between threads of processes at different times

• Running code in parallel

What is a benefit of concurrent processing in programming?

• Lower program throughput
• Reduced efficiency for complex problems
• Higher program throughput and reduced idle time
• Reduced complexity in code

What is a drawback of concurrent processing?

• Multiple threads may be stored in different storage locations

• One thread may require another to complete – causing a deadlock
• It requires a small amount of memory

• It speeds up program execution

What does a trace table help you with in programming?

• Debugging complex algorithms
• Identifying the purpose of an algorithm
• Finding out why an algorithm is not working correctly
• Good code maintenance
