MP3: Practice Test 1

What is a loop used for?

• To repeat a block of code multiple times

• To store data

• To define a function

• To handle errors

A While Loop runs until ________________.

• a specified condition is false.

• a specified condition is true.

• the loop has iterated 10 times.

• the program ends.

Define the following: a. Loop control variable b. Count Variable c. Initialize

What are the two ways of ending a loop?

• Using a break statement and reaching the end of the loop block

• Using a continue statement and reaching the end of the loop block

• Using a return statement and reaching the end of the loop block

• Using a goto statement and reaching the end of the loop block

For questions 5-7, what is output by each of the following loops? x = 10 while (x > 5): x = x - 1 print (x)

• 5, 6, 7, 8, 9

• 6, 7, 8, 9, 10

• 9, 8, 7, 6, 5

• 10, 9, 8, 7, 6

What is the output of the following loop? x = 1 while (x < 5): print (x) x = x + 2

• 1 3

• 1 2 3 4

• 1 2 3 4 5

• 1 3 5

What will be the output of the following code? ``` x = 1 while (x < 12): print (x) x = x + 3 ```

• 1 4 7 10

• 1 2 3 4 5 6 7 8 9 10 11

• 1 3 6 9

• 1 4 7 10 13

Identify whether the following loop is a user input loop or a count loop: Print the numbers 1 – 100, five per line.

• User Input

• Count

Identify whether the following loop is a user input loop or a count loop: Input the user’s name and print it to the screen 300 times.

• User Input

• Count

While loops should always be:

• output

• indented

• calculated

• input
