What is the purpose of the IF statement in pseudocode?

• It allows decision-making in the program by executing a block of code if a condition is true.

• It always executes a block of code regardless of a condition.

• It repeats a block of code for a fixed number of times.

• It assigns a value to a variable based on a condition.

Which of the following is a valid structure for an IF statement with an ELSE clause in pseudocode?

• IF X > 10 THEN OUTPUT "Greater" ELSE OUTPUT "Smaller"

• IF X > 10 OUTPUT "Greater" ELSE "Smaller"

• IF X > 10 OUTPUT "Greater" ELSE OUTPUT "Smaller"

• IF X > 10 OUTPUT "Greater" ELSE

What is a nested IF statement in pseudocode?

• An IF statement inside another IF statement.

• A loop inside an IF statement.

• An IF statement followed by a CASE structure.

• An IF statement with no ELSE clause.

What is the function of a CASE structure in pseudocode?

• It provides a way to choose between multiple alternatives based on a variable's value.

• It loops through a list of values.

• It checks conditions and executes a block of code repeatedly.

• It defines a conditional check for data validation.

Which of the following is a correct CASE structure in pseudocode?

• CASE X OF 1: OUTPUT "One", 2: OUTPUT "Two", 3: OUTPUT "Three"

• CASE X OF 1 OUTPUT "One" 2 OUTPUT "Two" 3 OUTPUT "Three"

• CASE 1 OUTPUT "One" 2 OUTPUT "Two" 3 OUTPUT "Three"

• CASE X: 1 OUTPUT "One", 2 OUTPUT "Two", 3 OUTPUT "Three"

What is a count-controlled loop in pseudocode?

• A loop that repeats a set number of times based on a counter.

• A loop that repeats until a condition is met.

• A loop that runs indefinitely.

• A loop that runs a fixed number of times until a condition changes.

Which pseudocode structure is used for a count-controlled loop?

• FOR X = 1 TO 10 DO OUTPUT X

• WHILE X 10 DO OUTPUT X

• IF X > 10 THEN OUTPUT "Greater"

What is a post-condition loop in pseudocode?

• A loop that executes at least once before checking the condition.

• A loop that checks the condition before executing any code.

• A loop that only runs if the condition is met.

• A loop that runs until a counter reaches a specific value.

Which pseudocode structure would you use for a post-condition loop?

• REPEAT UNTIL X > 10 DO OUTPUT X

• WHILE X > 10 DO OUTPUT X

• FOR X = 1 TO 10 DO OUTPUT X

• IF X > 10 THEN OUTPUT "Greater"

What is a pre-condition loop in pseudocode?

• A loop that checks the condition before executing any code.

• A loop that executes at least once before checking the condition.

• A loop that runs only if the condition is met.

• A loop that repeats a fixed number of times.
