Understanding Control Structures in Programming

This video tutorial covers the Cambridge Computer Science pseudocode guide, focusing on selection statements, loops, procedures, functions, and file handling. It explains the syntax and usage of if and case statements, different types of loops, and how to handle files in pseudocode. The tutorial also differentiates between procedures and functions, highlighting their syntax and use cases.

What is the purpose of using indentation in if statements?

• To reduce the number of lines

• To make the code easier to read

• To increase the complexity of the code

• To make the code run faster

In a case statement, what keyword is used to handle situations not covered by specific cases?

• default

• else

• otherwise

• none

Which loop is guaranteed to execute at least once?

• Postconditional loop

• While loop

• For loop

• Preconditional loop

In a for loop, what keyword is used to specify the increment value?

• Increase

• Step

• Add

• Next

In nested for loops, why is it important to specify which loop you are closing?

• To reduce the number of lines

• To make the code run faster

• To increase the complexity of the code

• To avoid confusion about which loop is being closed

What is the main difference between a procedure and a function?

• A procedure can have parameters, a function cannot

• A function returns a value, a procedure does not

• A procedure is faster than a function

• A function can only be used once

Which keyword is used to define a procedure in pseudocode?

• Method

• Function

• Define

• Procedure

Which file mode should you use if you want to add data to an existing file without deleting its contents?

• Overwrite

• Read

• Write

• Append

What keyword is used to close a file after operations are completed?

• Terminate

• Finish

• Close

• End

What is the purpose of the EOF function in file handling?

• To check if the file is empty

• To write data to a file

• To determine the end of a file

• To open a file
