Reducing the duplication of code is one of the advantages of using a loop structure

• True

• False

In a flowchart, both the decision structure and the repetition structure use the diamond symbol to represent the condition that is tested

• True

• False

Both of the following for clauses would generate the same number of loop iterations.

for num in range(4):

for num in range(1, 5):

• True

• False

To get the total number of iterations in a nested loop, add the number of iterations in the inner loop to the number in the outer loop.

• True

• False

What type of loop structure repeats the code based on the value of Boolean expression?

• Condition controlled loop

• count controlled loop

• number controlled loop

• boolean controlled loop

What are the values that the variable num contains through the iterations of the following for loop?

for num in range(2, 9, 2):

• 2 4 6 8

• 2 5 8

• 1 3 5 7 9

• 2 3 4 5 6 7 8 9

__________ is the process of inspecting data that has been input into a program in order to ensure that the data is valid before it is used in a computation.

• Correcting data

• Data Validation

• Correcting input

• Input validation

When will the following loop terminate?

while keep_on_going != 999:

• when keep_on_going refers to a value greater than 999

• when keep_on_going refers to a value equal to 999

• when keep_on_going refers to a value not equal to 999

• when keep_on_going refers to a value less than 999

In Python, the variable in the for clause is referred to as the __________ because it is the target of an assignment at the beginning of each loop iteration.

• count variable

• target variable

• for variable

• loop variable

Which of the following represents an example to calculate the sum of numbers (that is, an accumulator), given that the number is stored in the variable number and the total is stored in the variable total?

• number += number

• total + number = total

• total += number

• total = number
