Program Control Structures Assessment

What are the three basic types of control structures in programming?

• Input, Process, Output

• Sequence, Selection, Repetition

• Start, Process, End

• Variables, Constants, Arrays

Which loop structure will always execute at least once before checking the condition?

• For loop

• While loop

• Do…While loop

• If loop

When is a FOR loop most appropriate to use?

• When the loop needs to execute at least once

• When we don't know how many iterations are needed

• When we know the exact number of iterations needed

• When we need to check conditions after execution

In a WHILE loop, when is the condition checked?

• After executing the loop body

• Before executing the loop body

• Both before and after execution

• Only at program initialization

What is the correct syntax for a WHILE loop?

• while (condition) { statements }

• for (init; condition; increment) { statements }

• do while (condition) { statements }

• do { statements } while (condition);

If you need to print "Hello" exactly 10 times, which loop would be most efficient?

• Do…While loop

• While loop

• For loop

• If statement

What happens if the condition in a WHILE loop is false at the start?

• The loop executes once

• The loop body never executes

• The program crashes

• The loop executes infinitely

What is the primary difference between WHILE and DO…WHILE loops?

• WHILE loops can't be used for counting

• DO…WHILE guarantees at least one execution

• WHILE loops are faster

• DO…WHILE can only use numeric conditions
