Iteration Assessment

In programming, what is iteration?

• The repetition of steps within a program

• The order in which instructions are carried out

• A decision point in a program

Why is iteration important?

• It determines the order in which instructions are carried out

• It allows code to be simplified by removing duplicated steps

• It allows multiple paths through a program

What is iteration known as?

• Looping

• Crashing

• Repeating

Which two statements are used to implement iteration?

• IF..ELSE and WHILE

• DO and WHILE

• FOR and WHILE

In programming, what is a statement?

• A statement is a block of code

• A statement is a repeated instruction

• A statement is a single instruction

Which type of loop iterates until instructed otherwise?

• A condition-controlled loop

• A count-controlled loop

• A repeat-once loop

Look at the following code and identify the variables.

x=0

while x<4:

x=x+1

print ('x is ',+ x)

• 2 variables

• 1 variable

• 4 variables

• 3 variables

How many times will the variable loop?

for i in range (1,11):

i= i+i

print(i)

• 9

• 11

• 10

• 8

The following loop displays:

for i in range (1,11):

i= i+i

print(i)

• 18

• 20

• 10

• 19

• for

• if

• try

• while
