Unit 7 Mid Review

Algorithms can be created in all the following ways EXCEPT:

• creating from an idea

• combining existing algorithms

• removing sequencing, selection, and iteration from an algorithm

• modifying existing algorithms

Using existing algorithms as building blocks for new algorithms has all the following benefits EXCEPT:

• reduces development time

• reduces testing

• simplifies debugging

• removes procedural abstraction

What is one of the benefits of using a library in a program?

• simplifies creating a complex program

• increases development time

• removes all testing

• reduces abstractions in the program

Dividing a program into separate subprograms (such as libraries) is known as:

• modularity

• iteration

• API

• documentation

Modularity is defined as:

• modularity Dividing a program into separate subprograms (such as libraries)

• the repetition of a process

• a set of functions and procedures allowing the creation of applications that access the features or data of an operating system

• written specification and instructions accompanying a computer program

What number will be output by the console.log command on line 5?

• 10

• 11

• 12

• 13

• 16

What will be the order of letters printed to the console when this program is run?

• a b c

• a b c b c b c

• a b c b c

• a b c a

Which of the following is true of functions?

• Programs written with functions run more quickly

•   Functions can help remove repeated code from a program

• Replacing repeated code with a function will reduce the number of commands the computer needs to run

• Functions are called once but can be declared many times

What will the value of the variable bags be at the end of the flowchart shown here?

• 1

• 2

• 3

• 4

Putting commands in correct order so computers can read the commands.

• sequencing

• pattern matching

• function

• variable
